Various Kalpas - Verse 42

Sūta said: Since the great Goddess was seen as biped in the course of the rites, Gāyatrī the creator of the worlds is also of the same nature. Hence all human beings are bipeds, endowed with two breasts. Since the great goddess, the unborn deity of great strength, was seen by you as supporting all living beings, therefore, the subjects will have all kinds of form.
