1 Gita Sloka  Every Day - Chapter 15 - Purushottama Yoga - Sloka 15

Sarvasya chaham hrudi samnivishtah mattah smritih gyanam apa uhanam cha I

Vedaih cha sarvaih aham eva vedyah vedanta krut veda vid eva cha aham II sloka 15

सर्वस्य चाहं हृदि संनिविष्टः मत्तः स्मृतिः ज्ञानं अप ऊहनं  च I 

वेदैः च सर्वैः अहं एव वेद्यैः वेदान्त कृत वेद विद् एव च अहम् II श्लोक 15

And I am seated in the hearts of All; From me are memory, knowledge as well as their loss; I am verily that which has to be known by all the vedas; I am indeed the author of the vedanta as well as the knower of the vedas.

The Lord resides as the consciousness in the hearts of all. Memory of what has been done before is possible because of this. Knowledge or the faculty of understanding as to how to react to the changing circumstances- this power also comes from it. As the unwanted old records are destroyed, the purposeless retention in memory and the aimless fostering of unwanted knowledge - these are all done away with because of the proximity of the consciousness.

The various cosmic functions and the knowledge pertaining to them His omniscience is evinced verywhere in the nature by things sentient and insentient. This omniscience is attested by the cosmos and the nature which testifies that he is Bliss. That beauty is all his, is borne testimony to by anything and everything  in the universe.To know all these verities is to know the vedas. Iswara is the knower of the vedas. The truth of his being beyond all this is vedanta.
