Bhagavad Gita 18.63

इति ते ज्ञानमाख्यातं गुह्याद्गुह्यतरं मया।विमृश्यैतदशेषेण यथेच्छसि तथा कुरु॥

iti te jñānamākhyātaṃ guhyādguhyataraṃ mayā |vimṛśyaitadaśeṣeṇa yathecchasi tathā kuru ||

Thus, wisdom more secret than secrecy itself has been declared to you by me. Reflect on it fully, then act as you wish.

Thus, I have revealed to you the truth, the mystery of mysteries. Having thought it over, you are free to act as you wish.

Our plain-language meaning of this verse is waiting for scholar review.
