There are two who enjoy the fruits of their good deeds in the world, having entered into the cave of the heart, seated (there) on the highest summit. The knowers of Brahman call them shadow and light. So also (they are called) by householders who perform five fire- sacrifices or three Nachiketa fire-sacrifices.
May we be able to learn that Nachiketa fire-sacrifice, which is a bridge for those who perform sacrifice. May we also know the One, who is the highest imperishable Brahman for those who desire to cross over to the other shore which is beyond fear.
The senses are called the horses; the sense objects are the roads; when the Atman is united with body, senses and mind, then the wise call Him the enjoyer.
यस्त्वविज्ञानवान्भवत्यमनस्कः सदाऽशुचिः ।
न स तत्पदमाप्नोति संसारं चाधिगच्छति
yas tv avijñānavān bhavaty amanaskaḥ sadāśuciḥ / na sa tat padam āpnoti saṃsāraṃ cādhigacchati
He who does not possess discrimination, whose mind is uncontrolled and always impure, he does not reach that goal, but falls again into Samsara (realm of birth and death).
vijñānasārathir yas tu manaḥ pragrahavān naraḥ / so 'dhvanaḥ pāram āpnoti tad viṣṇoḥ paramaṃ padam
The man who has a discriminative intellect for the driver, and a controlled mind for the reins, reaches the end of the journey, the highest place of Vishnu (the All-pervading and Unchangeable One).
Beyond the great Atman is the Unmanifested; beyond the Unmanifested is the Purusha (the Cosmic Soul); beyond the Purusha there is nothing. That is the end, that is the final goal.
yacched vāṅmanasī prājñas tad yacchej jñāna ātmani / jñānam ātmani mahati niyacchet tad yacchec chānta ātmani
A wise man should control speech by mind, mind by intellect, intellect by the great Atman, and that by the Peaceful One (the Paramatman or Supreme Self).
Arise! Awake! Having reached the Great Ones (illumined Teachers), gain understanding. The path is as sharp as a razor, impassable and difficult to travel, so the wise declare.
aśabdam asparśam arūpam avyayaṃ tathārasaṃ nityam agandhavac ca yat / anādy anantaṃ mahataḥ paraṃ dhruvaṃ nicāyya tan mṛtyumukhāt pramucyate
Knowing That which is soundless, touchless, formless, undecaying; also tasteless, odorless, and eternal; beginningless, endless and immutable; beyond the Unmanifested: (knowing That) man escapes from the mouth of death.
ya imaṃ paramaṃ guhyaṃ śrāvayed brahmasaṃsadi / prayataḥ śrāddhakāle vā tad ānantyāya kalpate / tad ānantyāya kalpata iti
He who with devotion recites this highest secret of immortality before an assembly of Brahmanas (pious men) or at the time of Shraddha (funeral ceremonies), gains everlasting reward, he gains everlasting reward.
