Here is something you might not have seen before in your Jyotish studies: a visual depiction of the qualities (gunas) of the nakshatras.
The material is all taken from Hart de Fouw's excellent work: Light on Life, An Introduction to the Astrology of India (particularly pages 206-214).
As one bright student told me the other day, the nakshatras are kind of like the periodic table of Jyotish. Full of story and lore, truth and the telling, myth and math, nakshatras neatly introduce us to the more Tantric webs of meaning of Nature and of the Universe.
They are parts of the 360 degree zodiac, each of the 27 nakshatras being 13 degrees and 20 minutes. The 28th that is sometimes used is abhijit, but "only occasionally, in electional astrology" and its depiction would "ruin the symmetrical distribution" as well as mess up the divine geometry inherent within. (See Light on Life.)
Numbers are a quick and easy way to label the other standard nakshatras:
- Aśvinī
- Bharaṇī
- Kṛttikā
- Rohiṇī
- Mṛgaśīrṣa
- Ārdrā
- Punarvasu
- Puṣya
- Āśleṣā
- Maghā
- Pūrva Phalgunī
- Uttara Phalgunī
- Hasta
- Citrā
- Svātī
- Viśākhā
- Anurādhā
- Jyeṣṭhā
- Mūla
- Pūrvāṣāḍhā
- Uttarāṣāḍhā
- Śravaṇa
- Dhaniṣṭhā
- Śatabhiṣā
- Pūrva Bhādrapadā
- Uttara Bhādrapadā
- Revatī
Abhijit is acknowledged on the wheel as a thin dashed sliver between Uttara Ashadha (21) and Shravana (22), where it actually sits.
It is my belief and motivation that, by looking at these visual diagrams, new insights will come to the student, particularly for those, like me, who are pitta and visually oriented. Here is the wheel: one wheel, twelve layers. Choose a layer, hover a star, click it to see all twelve of its qualities at once. As always, contact me with any questions, comments, or observations, and I will include them here.
The Nakshatra Guṇa Wheel
27 stars · 12 layers · after Light on Life
Tattva
The twelve inner rings, from the outside in: Gaṇḍānta · Activity · Caste · Cycle · Direction · Gender · Doṣa · Nature · Guṇa · Yoni · Gaṇa · Tattva. The lit ring is the layer on display; click any ring to switch to it. Aśvinī begins at the top and the stars run clockwise; the outer numbers count them, the inner ring of glyphs marks the twelve rāśis.
A key to the twelve layers
- Gaṇḍānta the three knots
- Where a water sign ends and a fire sign begins, a rāśi boundary and a nakshatra boundary coincide: Karkaṭa→Siṃha (Āśleṣā→Maghā), Vṛścika→Dhanus (Jyeṣṭhā→Mūla) and Mīna→Meṣa (Revatī→Aśvinī). Light on Life calls this a double sandhi and finds grahas placed there weak and trouble-prone unless strengthened by remedies. The classical zone is the last pada of the water-side star and the first pada of the fire-side star, most intense within 48′ (two ghaṭikās) of the seam.Last pada of the water-side star — Āśleṣā · Jyeṣṭhā · Revatī — the sign ends in water
First pada of the fire-side star — Maghā · Mūla · Aśvinī — the sign begins in fire - Activity how the star pursues its aims
- How a star goes after what it wants. Active stars pursue knowledge eagerly and dynamically; passive stars are receptive — when the student is ready, the teacher appears; balanced stars hold both in proportion.Active (9): Kṛttikā, Āśleṣā, Maghā, Citrā, Viśākhā, Jyeṣṭhā, Mūla, Dhaniṣṭhā, Śatabhiṣā
Passive (9): Aśvinī, Mṛgaśīrṣa, Punarvasu, Puṣya, Hasta, Svātī, Anurādhā, Śravaṇa, Pūrva Bhādrapadā
Balanced (9): Bharaṇī, Rohiṇī, Ārdrā, Pūrva Phalgunī, Uttara Phalgunī, Pūrvāṣāḍhā, Uttarāṣāḍhā, Uttara Bhādrapadā, Revatī - Caste varṇa — the star's social temperament
- The star's natural propensities. Brāhmaṇa stars incline to learning, ritual and counsel; Kṣatriya to governance and protection; Vaiśya to trade; Śūdra to service and labour. Three classes stand outside the four: the servant or farmer, the butcher, and the mleccha — the outsider to the whole scheme. Kṛttikā and the three Pūrvās are Brāhmaṇa; Puṣya and the three Uttarās are Kṣatriya.Brāhmaṇa (4): Kṛttikā, Pūrva Phalgunī, Pūrvāṣāḍhā, Pūrva Bhādrapadā
Kṣatriya (4): Puṣya, Uttara Phalgunī, Uttarāṣāḍhā, Uttara Bhādrapadā
Vaiśya (3): Aśvinī, Punarvasu, Hasta
Śūdra (4): Rohiṇī, Maghā, Anurādhā, Revatī
Servant / farmer (4): Mṛgaśīrṣa, Citrā, Jyeṣṭhā, Dhaniṣṭhā
Butcher (4): Ārdrā, Svātī, Mūla, Śatabhiṣā
Mleccha (4): Bharaṇī, Āśleṣā, Viśākhā, Śravaṇa - Cycle creation · maintenance · dissolution
- Every third star carries one of the three cosmic functions — sṛṣṭi (creation), sthiti (maintenance), laya or saṃhāra (dissolution). The visionary who starts things lives in creation stars, the administrator who keeps them running in maintenance stars, the strategist who dismantles what has outlived itself in dissolution stars. The pattern is exact: each group holds the three stars of three Vimśottarī lords.Creation (sṛṣṭi) (9): Aśvinī, Rohiṇī, Punarvasu, Maghā, Hasta, Viśākhā, Mūla, Śravaṇa, Pūrva Bhādrapadā
Maintenance (sthiti) (9): Bharaṇī, Mṛgaśīrṣa, Puṣya, Pūrva Phalgunī, Citrā, Anurādhā, Pūrvāṣāḍhā, Dhaniṣṭhā, Uttara Bhādrapadā
Dissolution (laya) (9): Kṛttikā, Ārdrā, Āśleṣā, Uttara Phalgunī, Svātī, Jyeṣṭhā, Uttarāṣāḍhā, Śatabhiṣā, Revatī - Direction which way the star faces
- Upward-facing (ūrdhva-mukha) stars suit whatever rises — building storeys, planting trees, coronations, flight; downward-facing (adho-mukha) stars suit whatever goes below the surface — wells, foundations, mining, deep research; level-facing (tiryak-mukha) stars suit movement across the ground — journeys, roads, trading in animals. The three Uttarās look up, the three Pūrvās look down.Upward-facing (9): Rohiṇī, Ārdrā, Puṣya, Uttara Phalgunī, Uttarāṣāḍhā, Śravaṇa, Dhaniṣṭhā, Śatabhiṣā, Uttara Bhādrapadā
Downward-facing (9): Bharaṇī, Kṛttikā, Āśleṣā, Maghā, Pūrva Phalgunī, Viśākhā, Mūla, Pūrvāṣāḍhā, Pūrva Bhādrapadā
Level-facing (9): Aśvinī, Mṛgaśīrṣa, Punarvasu, Hasta, Citrā, Svātī, Anurādhā, Jyeṣṭhā, Revatī - Gender male · female · neuter
- Male, female and neuter stars. In Light on Life the chief use is judging the sex of children from the stars occupied by the relevant indicators, resolved by planetary strength when they disagree. Only three stars are neuter: Mṛgaśīrṣa, Mūla and Śatabhiṣā.Male (8): Aśvinī, Punarvasu, Puṣya, Hasta, Anurādhā, Śravaṇa, Pūrva Bhādrapadā, Uttara Bhādrapadā
Female (16): Bharaṇī, Kṛttikā, Rohiṇī, Ārdrā, Āśleṣā, Maghā, Pūrva Phalgunī, Uttara Phalgunī, Citrā, Svātī, Viśākhā, Jyeṣṭhā, Pūrvāṣāḍhā, Uttarāṣāḍhā, Dhaniṣṭhā, Revatī
Neuter (3): Mṛgaśīrṣa, Mūla, Śatabhiṣā - Doṣa vāta · pitta · kapha
- The star's constitution — the same triad that marriage-matching calls nāḍī (ādi, madhya, antya). It zig-zags around the wheel: vāta, pitta, kapha, kapha, pitta, vāta…Vāta (9): Aśvinī, Ārdrā, Punarvasu, Uttara Phalgunī, Hasta, Jyeṣṭhā, Mūla, Śatabhiṣā, Pūrva Bhādrapadā
Pitta (9): Bharaṇī, Mṛgaśīrṣa, Puṣya, Pūrva Phalgunī, Citrā, Anurādhā, Pūrvāṣāḍhā, Dhaniṣṭhā, Uttara Bhādrapadā
Kapha (9): Kṛttikā, Rohiṇī, Āśleṣā, Maghā, Svātī, Viśākhā, Uttarāṣāḍhā, Śravaṇa, Revatī - Nature the muhūrta temperaments
- The seven temperaments of muhūrta. Fixed stars for permanence; movable for travel and change; sharp (dreadful) for attack, exorcism and punishment; soft (tender) for friendship, love, ornament, music and marriage; fierce (severe) for destructive work; light (swift) for trade, healing, learning and the fine arts; and two mixed stars that are sharp and soft at once.Fixed (dhruva) (4): Rohiṇī, Uttara Phalgunī, Uttarāṣāḍhā, Uttara Bhādrapadā
Movable (cara) (5): Punarvasu, Svātī, Śravaṇa, Dhaniṣṭhā, Śatabhiṣā
Sharp (tīkṣṇa) (4): Ārdrā, Āśleṣā, Jyeṣṭhā, Mūla
Soft (mṛdu) (4): Mṛgaśīrṣa, Citrā, Anurādhā, Revatī
Mixed (miśra) (2): Kṛttikā, Viśākhā
Fierce (ugra) (5): Bharaṇī, Maghā, Pūrva Phalgunī, Pūrvāṣāḍhā, Pūrva Bhādrapadā
Light / swift (kṣipra) (3): Aśvinī, Puṣya, Hasta - Guṇa sattva · rajas · tamas
- Sattva, rajas and tamas as assigned in Light on Life: each star carries the guṇa of its Vimśottarī lord — Jupiter's and Mercury's stars are sāttvic, those of Venus, the Sun and the Moon rājasic, those of Mars, Saturn, Rāhu and Ketu tāmasic.Sattva (6): Punarvasu, Āśleṣā, Viśākhā, Jyeṣṭhā, Pūrva Bhādrapadā, Revatī
Rajas (9): Bharaṇī, Kṛttikā, Rohiṇī, Pūrva Phalgunī, Uttara Phalgunī, Hasta, Pūrvāṣāḍhā, Uttarāṣāḍhā, Śravaṇa
Tamas (12): Aśvinī, Mṛgaśīrṣa, Ārdrā, Puṣya, Maghā, Citrā, Svātī, Anurādhā, Mūla, Dhaniṣṭhā, Śatabhiṣā, Uttara Bhādrapadā - Yoni sexual type — creature and sex
- The star's sexual type: a creature and its sex. Like creatures pair most easily — each animal has a male star and a female star (the mongoose stands alone) — while the seven natural enmities clash: horse–buffalo, elephant–lion, sheep–monkey, serpent–mongoose, dog–deer, cat–rat, cow–tiger. Hover a star to see its mate and its enemies.Horse (aśva): ♂ Aśvinī · ♀ Śatabhiṣā — enemy: buffalo
Elephant (gaja): ♂ Bharaṇī · ♀ Revatī — enemy: lion
Sheep (meṣa): ♂ Puṣya · ♀ Kṛttikā — enemy: monkey
Serpent (sarpa): ♂ Rohiṇī · ♀ Mṛgaśīrṣa — enemy: mongoose
Dog (śvāna): ♂ Mūla · ♀ Ārdrā — enemy: deer
Cat (mārjāra): ♂ Āśleṣā · ♀ Punarvasu — enemy: rat
Rat (mūṣaka): ♂ Maghā · ♀ Pūrva Phalgunī — enemy: cat
Cow (go): ♂ Uttara Phalgunī · ♀ Uttara Bhādrapadā — enemy: tiger
Buffalo (mahiṣa): ♂ Svātī · ♀ Hasta — enemy: horse
Tiger (vyāghra): ♂ Viśākhā · ♀ Citrā — enemy: cow
Deer (mṛga): ♂ Jyeṣṭhā · ♀ Anurādhā — enemy: dog
Monkey (vānara): ♂ Pūrvāṣāḍhā · ♀ Śravaṇa — enemy: sheep
Mongoose (nakula): ♂ Uttarāṣāḍhā · no female star — enemy: serpent
Lion (siṃha): ♂ Pūrva Bhādrapadā · ♀ Dhaniṣṭhā — enemy: elephant - Gaṇa divine · human · demonic
- Divine (deva), human (manuṣya) and demonic (rākṣasa) temperaments — the gaṇa-kūṭa of matching. Like with like is easiest; deva with rākṣasa is the classic friction.Divine (deva) (9): Aśvinī, Mṛgaśīrṣa, Punarvasu, Puṣya, Hasta, Svātī, Anurādhā, Śravaṇa, Revatī
Human (manuṣya) (9): Bharaṇī, Rohiṇī, Ārdrā, Pūrva Phalgunī, Uttara Phalgunī, Pūrvāṣāḍhā, Uttarāṣāḍhā, Pūrva Bhādrapadā, Uttara Bhādrapadā
Demonic (rākṣasa) (9): Kṛttikā, Āśleṣā, Maghā, Citrā, Viśākhā, Jyeṣṭhā, Mūla, Dhaniṣṭhā, Śatabhiṣā - Tattva the five elements
- The five great elements in five contiguous bands of the zodiac: earth (Aśvinī–Mṛgaśīrṣa), water (Ārdrā–Pūrva Phalgunī), fire (Uttara Phalgunī–Anurādhā), air (Jyeṣṭhā–Śravaṇa), ether (Dhaniṣṭhā–Revatī). Hover a star to see which elements cooperate with it — the rules are set out below the wheel.Earth (pṛthvī) (5): Aśvinī, Bharaṇī, Kṛttikā, Rohiṇī, Mṛgaśīrṣa
Water (jala) (6): Ārdrā, Punarvasu, Puṣya, Āśleṣā, Maghā, Pūrva Phalgunī
Fire (agni) (6): Uttara Phalgunī, Hasta, Citrā, Svātī, Viśākhā, Anurādhā
Air (vāyu) (5): Jyeṣṭhā, Mūla, Pūrvāṣāḍhā, Uttarāṣāḍhā, Śravaṇa
Ether (ākāśa) (5): Dhaniṣṭhā, Śatabhiṣā, Pūrva Bhādrapadā, Uttara Bhādrapadā, Revatī
Cooperation rules for the tattvas
Each nakshatra belongs to one of the five great elements, and the elements have manners with one another. Light on Life gives the rules; here they are, with the reasoning of the elements themselves:
- Fire and air cooperate. Air feeds fire; fire sets air moving.
- Earth and water cooperate. Water gives earth its life; earth gives water a shape to hold.
- Ether cooperates indiscriminately with every other tattva. It is the space in which the other four act, so it obstructs none of them.
- Earth does not cooperate with fire — and especially not with air. Fire scorches and cracks the earth; air scatters it.
- Water does not cooperate with air — and especially not with fire. Air dries water away as cloud; fire boils it off entirely.
- Two stars of the same tattva are kindred and cooperate as a matter of course.
Read from the other side, the same rules say: fire does not cooperate with earth and especially not with water; air does not cooperate with water and especially not with earth. The matrix holds all twenty-five pairings — hover a cell.
A chart example: when the lords of the 1st and the 7th cannot cooperate
The rules become useful the moment two significators are compared. Take the lord of the 1st house (the native, the self) and the lord of the 7th (the partner, the marriage), and look at the nakshatras they occupy. When the tattva of the lagna lord's star does not cooperate with the tattva of the 7th lord's star, marriage — or happiness within it — may be obstructed, delayed, or repeatedly interrupted. When the two tattvas cooperate, the same axis flows.
Siṃha (Leo) rises, so the Sun rules the 1st house and Saturn the 7th. Each planet is drawn in the first pada of the star you choose; the small numbers are the rāśis. Read it as one thread in the whole cloth — house placement, dignity, aspects and daśā still have their say.
Light on Life itself illustrates the same logic between a graha's own tattva and the star it occupies: a Siṃha-rising woman whose seventh lord Saturn — an airy graha — sat in the twelfth house in watery Puṣya, air and water not cooperating, spent much of her adult life unmarried while wishing for a relationship. The first preset above puts that Saturn back in Puṣya and lets the lagna lord's fire meet it.

A note on the lists
The classifications follow Light on Life (pp. 206–214), cross-checked against Hank Friedman's de Fouw-based table and the classical muhūrta lists (Muhūrta Cintāmaṇi and its kin). Where the book's printed lists are incomplete or at odds with the classical ones, the wheel follows the classical reading:
- Varṇa: Light on Life prints only three Brāhmaṇa and three Kṣatriya stars; the wheel follows the classical Muhūrta lists, in which Pūrva Phalgunī joins Kṛttikā and the Pūrvās (Brāhmaṇa) and Uttara Phalgunī joins Puṣya and the Uttarās (Kṣatriya).
- Direction: the book's printed lists swap the two Phalgunīs and omit Śatabhiṣā; the classical lists (all three Uttarās upward, all three Pūrvās downward, Śatabhiṣā upward) are used.
- Nature: Mṛgaśīrṣa is placed with the soft (mṛdu) stars, as in the classical lists and Friedman's table; the book's text has it among the mixed stars.
- Doṣa: the book's kapha list runs to eight stars; Maghā, the ninth, is restored from the nāḍī sequence.
- Yoni sexes and the seven enmities follow the classical yoni-kūṭa table; the gaṇḍānta zones (one pada, with a 48′ core) follow the classical definition.
Coming soon: some sort of visual treatment for the 4 padas per nakshatra, raising the number of elements to the holy number of 108.
Note, August 2026: the original diagrams were a PDF that did not survive the site's move; the interactive wheel above replaces them.
