When I first read the Bhagavad Gita, I was charmed and intrigued by the nicknames of Arjuna, the great everyday hero of the tale who represents nothing less than what it is to be human and reckon with one's true dharma.
Wikipedia summarizes the etymology and epithets of Arjuna. A Quora post on it is here.
I was delighted to see these names, my friends, all in one place. This list also got me thinking. It reminded me of Katapayadi, Ka·ṭa·pa·yā·di is an ancient cryptographic method used to embed extra layers of meaning in texts. Here is my calculator that uses this method to decrypt Sanskrit text into Jyotishical meaning.
Upon applying the calculator to the twelve names of Arjuna, I was amazed but not surprised to see that they map on to the twelve signs of the zodiac. (You can use this dictionary to obtain the proper protocol for inputting the names into the calculator. )
The following is the name, the meaning, and the sign for each of the appellations as re-ordered to the proper sequence in the sky. What I do not know off the top of my head is whether the order of appearance of the names in the Gita is in this sequence. I will look this up and comment below if I find this to be true.
Parantapa – one who concentrates the most, destroyer of enemies. ARIES
Shvethavāhana – one with milky white horses mounted to his pure white chariot. TAURUS
Shyamal - one who brings greenary, prosperous, beautiful environment and good nature to the region where ever he goes. GEMINI
Vijaya – always victorious, invincible and undefeatable. CANCER
Gāndīvadhanvan – one who possessed the mighty bow named Gandiva which was created by Lord Brahma. LEO
Phalguna – born under the star Uttara Phalguni This star is in VIRGO.
Savyasāchi – ambidextrous, only Arjuna was expert in using both hands equally in archery. LIBRA
The word Arjuna itself means "white", "clear", "shining" and "silver". SCORPIO [The connection between meaning and sign here may refer to alchemy as a Scorpionic 8th house expression as connected to the physical qualities of alchemy's metallic rasayanas. I also think that the name of Arjuna as Scorpio is reminiscent of the first verse of the Tao Te Ching that is variously translated with my favorite one saying "darkness within darkness, the gateway to all mystery". In a sense, Arjuna's plight is a darkness and his humanity in that plight may be the darkness within darkness. His journey, if we ourselves can follow it, may be the gateway that opens the door to all mystery. Also, mystery is an eighth house indication in Jyotish.]
Mahabahu - the one with extraordinary biceps, a perfect nickname for the archer. SAGITTARIUS
Jishnu – triumphant. CAPRICORN
Bībhatsu – one who always fights wars in a fair, stylish and terrific manner. AQUARIUS
Anagha - the one with pure soul. PISCES
As you can see the meaning of the name goes well with the tantric meaning of the Katapayadi-given sign for each of the twelve of them. So amazing!
