Bhagavad Gita 18.63

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

इति ते ज्ञानमाख्यातं गुह्याद्गुह्यतरं मया।विमृश्यैतदशेषेण यथेच्छसि तथा कुरु॥

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