Bhagavad Gita Chapter 15.15
sarvasya cāhaḿ hṛdi sanniviṣṭo
mattaḥ smṛtir jñānam apohanaḿ ca
vedaiś ca sarvair aham eva vedyo
vedānta-kṛd veda-vid eva cāham
I am seated in everyone’s heart, and from Me come remembrance, knowledge and forgetfulness. By all the Vedas, I am to be known. Indeed, I am the compiler of Vedanta, and I am the knower of the Vedas.
