Srimad Bhagavad Gita -Ramanujacharya
Chapter-15 Puruṣottama Yogaḥ
iti guhyatamaṃ śāstram idam uktaṃ mayā’nagha |
“I have revealed to you the most profound of all mysteries about Me as the Supreme Being, because you are worthy to receive this instruction due to being sinless. By understanding this, one will become truly wise and will have fulfilled all duties. — whatever knowledge has to be gained for attaining Me, is hereby acquired and whatever obligation has to be fulfilled in this connection — all that is to be taken as fulfilled by knowing this (the Purushottama Vidya).” In this stanza it is intimated that the knowledge of the Supreme Being acquired through the Scriptures achieves all this, but it does not give direct experience of God.
iti śrīmad bhagavad gītāsūpaniṣatsu brahma-vidyāyāṃ yoga-śāstre śrī kṛṣṇārjuna saṃvāde puruṣottama yogo nāma pañcadaśo’dhyāyaḥ
