Māndukya 1.03

In the waking state, the consciousness is directed outward, characterized by seven limbs and nineteen mouths, and it experiences the gross objects. The first form of the lord that giverns this is known as Vaiśvānara.

Bhāshya 1.03

A testimonial from the ancient text of Mahāyog is referenced, explaining the four forms of Lord Vishnu, the first being 'Vaiśvānara'. He is called 'Viśvaṃ', i.e. the Universal, as He is perceptible to all in gross form as the Universe, and also is the cause of all. He is also 'Nara' i.e. the man, associated with that Universal form, who is without destruction, hence is called 'Vaiśvānara'.

"The eternal Supreme Person resides in the body in four forms: Vaiśvānara, the waking state, the form with an elephant face.

The creator, who is beyond the perception of the external consciousness of living beings, possesses eighteen faces and entirely male forms.

The middle one is an elephant-shaped superhuman with, four-arms, two feet, and a trunk, thus is said to be seven-limbed.

His senses enjoy gross pleasures, but not the inauspicious ones. He is called "Viśvaṃ", the Universal, as is perceptible to all, and also is the cause of all.

He is "naraḥ" - the man, associated with that Universal form, who is without destruction, hence is called "Vaiśvānara". Lord Vinayaka, through meditation on the universal "Vaiśvānara" form and that of "taijasa", the luminous one, attained the form of an elephant-faced deity. In the same way, Indra attains the state of being Indra through the threefold meditation (on Vaiśvānara, taijasa, and Prajna i.e. the knowledgeable one). Through the fourfold meditation (on Vaiśvānara, taijasa, Prajna, and Turiya i.e. beyond the third or fourth), Rudra attains the state of being Rudra from Janardana. Thus, Vishnu, having qualities of existence, is the fourfold Ātmān, and is supreme and beyond.

- stated thus in the ancient text of Mahāyog.
