idaṃ dadyāddvijātīnāṃ sādhūnāmātmajasya vā |
suhṛdāṃ ca japetkarṇe śiṣyasyānugatasya vā || 63 ||

That regenerate person who is fully conversant with the Vedas and who, regarding this life to be exceedingly unstable, casts off his body on those mountains, abstaining from all food and drink in accordance with the rites laid down in the scriptures, after having adored the deities and bent his head in worship of the ascetics, is sure to attain to success and proceed to the eternal regions of Brahman. There is nothing unattainable to him who resides in a tirtha, restraining lust and subjugating wrath, in consequence of such residence. For the purpose of repairing to all the tirthas in the world, one should mentally think of those amongst them that are almost inaccessible or sojourns to which are attended with insurmountable difficulties. Sojourns to tirthas is productive of the merits of sacrifices. They are competent to cleanse everybody of sin. Fraught with great excellence, they are capable of leading to heaven. The subject is truly a great mystery. The very deities should bathe in tirthas. To them also they are sin-cleansing. This discourse on tirthas should be imparted to Brahmanas, and to such honest or righteous persons as are bent upon achieving what is for their own good. It should also be recited in the hearing of one's well-wishers and friends and of one's obedient and devoted disciples. Angiras possessed of great ascetic merit, had imparted this discourse to Gautama. Angiras himself had obtained it from Kasyapa of great intelligence.
