Janaka, Emperor of Videha, rose from his lounge, humbly approached Yajnavalkya and said - "Salutation to you, O Yajnavalkya. Please instruct me". Yajnavalkya said - "Your Majesty, as one who wishes to go a long distance would procure a chariot or a ship, even so you have fully equipped your mind with so many secret names of Brahman. You are also honoured and wealthy; you have studied the Vedas and heard the Upanishads. But do you know where you will go when you are released from this body? Emperor said - "Venerable Sir, I do not know where I shall go." Yajnvavalkya - "Then I will tell you where you will go." Emperor - "Tell me, venerable Sir."
The person who is in the right eye is named Indha. Though he is Indha, people call him by the indirect name Indra; for the gods are fond of indirect names and hate to be addressed directly.
The person who is in the left eye is his wife, Viraj (matter). The akasa (space) that lies within the heart is their place of union. Their food is the lump (pinda) of blood in the heart. Their wrap is the net-like structure in the heart. The path on which they move from sleep to waking is the nerve that goes upward from the heart; it is like a hair split into a thousand parts. In the body there are nerves called hita, which are placed in the heart. Through these the essence of our food passes as it moves on. Therefore, the subtle body (Taijasa) receives finer food than the gross body (Vaisvanara).
Of the illumined sage who is identified with Prajna in deep sleep the east is the eastern vital breath (prana), the south is the southern vital breath, the west is the western vital breath, the north is the northern vital breath, the upper direction is the upper vital breath, the direction below is the nether vital breath, and all the directions are all the vital breaths. This self is That which has been described as 'Not this, not this.' It is imperceptible, for It is never perceived; undecaying, for It never decays; unattached, for It is never attached; unfettered, for It never feels pain and never suffers injury. Verily, O Janaka, you have attained That which is free from fear - said Yajnavalkya. Venerable Yajnavalkya - said Emperor Janaka, "may that fearless Brahman be yours too, for you have made known to us the fearless Brahman. Salutations to you! Here is the Empire of Videha and also me at your service."
