सर्वस्य चाहं हृदि सन्निविष्टो मत्तः स्मृतिर्ज्ञानमपोहनं च | वेदैश्च सर्वैरहमेव वेद्यो वेदान्तकृद्वेदविदेव चाहम् ||
sarvasya cāhaṁ hṛdi sanniviṣṭo mattaḥ smṛtir jñānam apohanaṁ ca vedaiś ca sarvair aham eva vedyo vedānta-kṛd veda-vid eva cāham
Translation
And I am seated in the hearts of all; from Me come memory, knowledge, and their removal. I alone am to be known through all the Vedas; I am the author of Vedanta, and I am the knower of the Vedas.
Interpretation
One of the chapter's most intimate verses: Krishna dwells in the heart of every being as the Antaryami — the inner controller and witness. From him springs memory (the capacity to recall past experience), knowledge (understanding of present reality), and their removal (forgetting, the merciful erasure that allows movement forward). Even more: the entire Vedic tradition — all its scriptures, all its practices — has Krishna as both its ultimate subject (the One to be known) and its author (the inspiration behind Vedanta, the culminating teaching). The seeker of truth and the truth being sought are the same.
