saiṣā hy upaniṣad brāhmī pūrveṣāṁ pūrva-jair dhṛtā
saiṣā hy upaniṣad brāhmī pūrveṣāṁ pūrva-jair dhṛtā |
śraddhayā dhārayed yas tāṁ kṣemaṁ gacched akiñcanaḥ ||
(Śrīmad Bhāgavatam: 10.87.3)
“One who can adhere with śraddhā to this renowned Upaniṣad [i.e., this esoteric knowledge], related to Brahman and adhered to by the predecessors of our ancestors [i.e., by those such as Sanaka who came before Nārada and others], can become detached [i.e, free from adjuncts beginning with the body, or, free from possessiveness, that is, one can become an unalloyed bhakta] and attain weal [i.e., the supreme abode, or, bhakti-yoga, or Bhagavān’s lotus feet].
