Note 4 — Chapter CIV · Establishment of the Non-entity of the World.
Viharilala Mitra translation
Note.—The sky or vacuum is the taumatra or identic with the sound or word; and the void and its sound are both uncreated and eternal. (sabdho ajonitáth शब्दोऽयोनित्वात्). So it said:—In the beginning was the word (sound), the word was with god (vacuity), and the word was god (atmá), the spirit or air.
