Therefore, the soul is composed of Indha, who in the context of Creation is prana, the fundamental energy, and Viraj, who is the diversity-producing principle.
4 of the Mandukya Upanishad Agama-prakarna reads:- which means:- “The second quarter (Pada) is Taijasa whose sphere of activity is the dream state, who is conscious of the internal world of objects, who has seven limbs and nineteen mouths and who enjoys the subtle objects of the mental world.” Reality Consciousness conditioned by its own identifications with the subtle body becomes the dreamer and experiences the dream-world as Taijasa.
The waking-state-ego has nineteen mouths – the five organs of action, the five aspects of Prana, the vital breath, the mind, intellect, egoity and citta.
[3] Taijasa, the Luminous and whose sphere of action is dream, and who is the inward oriented consciousness, is the sound syllable U of Aum because it is exalted and because it is intermediate, it occurs between A and M referring equally to Vaisvanara and Prajna which two are, therefore, identical but itself being an unreal appearance, a phantom.
Sattva is called Taijasa because of its illuminating capacity but from which quality evolve, in addition to the manas-tattva, the five organs or faculties of sense.
