10.33 Of letters I am the alphabet 'a', which is the base of all letters as established in the Sruti:  'The letter 'a' itself is all speech' (Ai. Ai., 3.2.3). Samasika means collection of compound words. In it, I am the Dvandva compound; it is eminent because the meanings of both constituent terms are important. I am Myself imperishable Time composed of (divisions like) Kala, Muhurta etc. I am the four-faced Hiranyagarbha who is the creator of all.
