H. P. Blavatsky

Virâj. The Hindu Logos in the Purânas; the male Manu, created in the female portion of Brahmâ’s body (Vâch) by that god. Says Manu: “ Having divided his body into two parts, the lord (Brahmâ) became with the one half a male and with the other half a female; and in her he created Virâj”. The Rig ‐Veda makes Virâj spring from Purusha, and Purusha spring from Virâj. The latter is the type of all male beings, and Vâch, Sata‐rûpa (she of the hundred forms), the type of all female forms.
