Kaushitaki-Upanishad: First Adhyaya

He (at the time of death), having reached the path of the gods, comes to the world of Agni (fire), to the world of Vayu (air), to the world of Varuna, to the world of Indra, to the world of Pragapati (Virag), to the world of Brahman (Hiranyagarbha). In that world there is the lake Ara , the moments called Yeshtiha , the river Vigara (age-less), the tree Ilya , the city Salagya, the palace Aparagita (unconquerable), the door-keepers Indra

and Pragapati, the hall of Brahman, called Vibhu (built by vibhu, egoism), the throne Vikakshana (buddhi, perception), the couch Amitaugas (endless splendour), and the beloved Manasi (mind) and her image Kakshushi (eye), who, as if taking flowers, are weaving the worlds, and the Apsaras, the Ambas (sruti, sacred scriptures), and Ambayavis (buddhi, understanding), and the rivers Ambayas (leading to the knowledge of Brahman). To this world he who knows this (who knows the Paryanka-vidya) approaches. Brahman says to him: 'Run towards him (servants) with such worship as is due to myself. He has reached the river Vigara (age-less), he will never age.

4. Then five hundred Apsaras go towards him, one hundred with garlands in their hands, one hundred with ointments in their hands, one hundred with perfumes in their hands, one hundred with garments in their hands, one hundred with fruit in their hands. They adorn him with an adornment worthy of Brahman, and when thus adorned with the adornment of Brahman, the knower of Brahman moves towards Brahman (neut.) He comes to the lake Ara, and he crosses it by the mind, while those who come to it without knowing the truth , are drowned. He comes to the moments called Yeshtiha, they flee from him.

He comes to the river Vigara, and crosses it by the mind alone, and there shakes off his good and evil deeds. His beloved relatives obtain the good, his unbeloved relatives the evil he has done. And as a man, driving in a chariot, might look at the two wheels (without being touched by them), thus he will look at day and night, thus at good and evil deeds, and at all pairs (at all correlative things, such as light and darkness, heat and cold, &c.) Being freed from good and freed from evil he, the knower of Brahman (neut.), moves towards Brahman.
