The purport of this verse is that "I am situated in everyone's heart." Sarvasya cāhaṁ hṛdi sanniviṣṭo. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna (BG 18.61). Everyone's heart, Kṛṣṇa is there, or the Paramātmā is there. And mattaḥ smṛtir jṣānam apohanaṁ ca: and all the speculation or real understanding or forgetfulness or real knowledge, they are coming, being initiated from Him. Mattaḥ: "from Me." Smṛtir means memory; jṣāna means knowledge. Apohanaṁ ca: "forgetfulness." Everything is . . . forgetfulness is also from Him. Knowledge is also from Him. Memory is also from Him.
And vedais, vedais means all books of knowledge. Vedaiś ca sarvair. Sarvair means all varieties. It is not that simply the four Vedas, as we accept in India, Sāma, Yajur, Ṛg, Atharva. No. Any authorized scripture, that is Vedas. Any authorized scripture. Vedaiś ca sarvair. "All kinds of Vedas, they are searching after Me." The knowledge . . . actually, the destination of knowledge, as Śrīman Janārdana . . .
What we are searching after? He has summarized that we are searching after happiness. That's a fact. But we do not know where the happiness is there. That is our . . . searching, I am . . . subject matter of searching is happiness. Everyone in this material world is after happiness. But unfortunately, one has no information where is the happiness.
That remembrance can be . . . where is the happiness? That can be had from the Supersoul, who is sitting with you within your heart. Within your heart. Because Kṛṣṇa says that "I am sitting in everyone's heart as Supersoul, and from Me, intelligence, memory, knowledge, forgetfulness—everything—is being happened."
