Meaning of varAh-nAsI (Varanasi) as given in jAbAla upanishad

jAbAla upanishad explains the meaning of Varanasi in chapter II

II-2. ‘Which is that (place) where Avimukta (Siva) is established ?’

 ‘He is established in between varana and nasi’. 

‘What is (meant by) varana and what (by) nasi ?’ 

‘The varana is so called as it wards off all the faults committed by the (ten) organs (of perception and action). 

The nasi is so named as it destroys all sins committed by the (ten) organs. (The place between the varana and the nasi is the meeting place of the upper part of the nose and the centre of the eye brows). 

‘Which is the seat of that (Avimukta) ?’ 

‘That, which is the (well known) juncture of the eye brows and the nose, is the juncture of heaven (in the form of the crown of the head) and this world (in the form at the end of the chin). The knowers of the Veda worship indeed this juncture (Samadhi) as Sandhya (in their daily worship). That Avimukta is to be worshipped. He who knows this thus (the true nature of the Avimukta), imparts the wisdom of the Avimukta (that the individual Self is no other than the attributeless Brahman, to his disciples).

After Death Rites for Self Realized (Jnani)

In Paingala Upanishad, after death rites of Self Realized soul (Jnani) are given. 

IV-6. Upto (the exhaustion of) the operative deeds, the homeless liberated Self, behaves like the Slough of a snake, like the moon (in the sky).

IV-7. Shedding the body in a holy spot or (may be) in the home of an eater of dog’s flesh, (the liberated one) attains Isolation (Liberation).

IV-8. Afterwards, make an offering of his body to the cardinal points or bury (his body). Mendicancy (practice of begging) is prescribed for the male, never for the other.

IV-9. No observance of (the period of) pollution, no burning (of the corpse), no offering of rice balls or of water, no fortnightly rites (are laid down) for a mendicant who has become Brahman.

IV-10. There is no burning of what is (already) consumed, just as there is no cooking of what is (already) cooked. For one whose body is consumed in the fire of knowledge there is neither ceremonial rice offering nor any (other) rite (of obsequies).

IV-11. As long as the adjuncts (body, etc.,) persist, let one wait upon the teacher. Let him treat the wife of the teacher and his children as he does the teacher himself.

IV-12. When with the knowledge, ‘I am That !’ ‘I am That’ — I, whose mind is pure essence, is pure Spirit, is long-suffering – wisdom is won, when the object of knowledge, the supreme Self, is established in the heart; when the body is dissolved in the state of achieved Peace, then one becomes destitute of the luminous mind and intellect.

IV-13. Of what use is water to one who has had his fill of ambrosia ? Similarly, (for one) who has known his Self, of what use are the Vedas ? No duty remains for the Yogin who has had his fill of the ambrosia of knowledge. If duty be there, he is no knower of Truth. Though stationed at a distance, he is not distant; though embodied, he is disembodied; he is the omnipresent inner self.
