Body consists of mainly Seven chakras as I discuss here. In the Netra Tantra book I have; in the introductory preface part it is written:
Muladhara, Swadhisthana, Manipura, Anahat, Shakini and Ajna these six chakra contains lotus petals from 'अ' / 'A' to 'क्ष' / 'Ksha' for 50 letters of alphabet made yantra. Muladhara etc.. from this order contains petal numbers in the order 4, 6, 10, 12, 16 and 2. ie. Muladhara contains 4 and Ajna contains 2 letters. Or kundalini which is also called Chidagni or Chaitanya (Consciousness).....
This means that each petal consists seperate letters (varnas) and total is 4 + 6 +10 +12 + 16 +2 = 50 which is formed like a Yantra in the body.
What are the letters associated with each Chakra which forms this Yantra? I'm mainly wanting answers from Agamas/Tantras.
