यस्मिन्देवाश्च वेदाश्च पवित्रं कृत्स्नमेकताम् ।व्रजेत्तन्मानसं तीर्थं तत्र स्नात्वामृतो भवेत् ॥
In plain words
There is a place where the gods, the Vedas, and everything holy come together into one — and that place is the mind. That is the tīrtha. Bathe there, and you are deathless.
Close to the Sanskrit
In which the gods and the Vedas and the whole of what purifies come to oneness — that is the tīrtha made of mind; having bathed there, one would become deathless.
