A very brief analysis on the theory of fire from an Ayurvedic and Jyotish perspective:
Fire element has lately been on my mind. Mars has been strong in Scorpio, its own sign, the last couple of months, and even now, in Sagittarius, it continues to be strong.
My own inward pitta has been quite high, befitting the transits, a surge in thinking about fire has flowed forth, and my appreciation of the special place of fire has increased. I hope to show you why.
The five elements in the theory of yoga, Ayurveda, and Jyotish are
I have written before of how the knowing of them is at least equal in beauty, power, and insight as knowing the periodic table.
There are three pitta planets in Jyotish:
The chemistry of combustion is relevant here.
According to the linked material, combustion can happen in only two ways:
1. the relatively unusual method without carbon, used with rocket fuel, e.g.
Here, vata is completely transformed to pitta (the combination of water and fire). Since space element is on both sides of the equation, in effect, air is transformed to pitta.
2. the more common method with carbon, used with charcoal, e.g.
where z = x + y/4.
Here earth and air are completely transformed to air and pitta. Since air is on both sides of the equation, in effect, earth is transmuted to pitta.
Thus, only pitta represents transformation itself.
Kapha can not be transformed into Vata, nor vice versa.
Earth and air can become pitta through methods 1 and 2 above, but again, not vice versa.
Pitta truly is at the apex of the equilateral triangle representing the three doshas of vata, pitta, and kapha.
It is appropriate then that the tantric symbol for fire is the triangle.
which even looks like a flame.
We see this everywhere.
To be sure, fire is needed for any transformation, and transformation is
The heat is tamas, Mars. That is why Mars is a tamasic graha.
The light is Sun. Sattva. That is why the Sun is a sattvic graha.
The flame itself is highly movement-oriented, and rajasic, movement for movement's sake, and may be represented by Ketu.
Thus, pitta represent all three of the mahagunas of sattva, rajas, and tamas.
Finally, to increase your own pitta, including sadhaka pitta of brilliance of the brain, know that fire requires the twin fuels of carbon and oxygen, of earth and air. (Space as well, but that is assumed and everywhere in the equations, unchanging, unmoving, perfect, and everywhere.)
Increase your pitta by eating well (the fuel of carbon) and breathing well (the fuel of oxygen).
Everything else will surely take care of itself, the flames moving to a dance of their own accord, transforming you in a way you can trust, in a way that is uniquely complete.
Thus, only pitta involves the totality of life, the totality of the material universe, of all five of the five elements, as well as all three of the mahagunas.
Fire is life.
Perhaps this is why the all-important first word of the Rig Veda is agni, flame, and perhaps this is why Dr. Lad says that agni, our own inner flame, is our life, its measure, its potential, and its meaning.
This is why one must attend to one's own inner pilot light, one's cellular agni, so that the flames of perception, transformation, and power are lit appropriately. Do you feel your agni may be low? No need for worry. There are herbs for that.
