Bhagavad Gita 15.15 · Sarvasya Chaham Hridiसर्वस्य चाहं हृदि सन्निविष्टो मत्तः स्मृतिर्ज्ञानमपोहनं च।वेदैश्च सर्वैरहमेव वेद्यो वेदान्तकृद्वेदविदेव चाहम् ॥

I am seated in the hearts of all sentient beings as their innermost Self. Therefore from Me, the Self of all beings, are memory, knowledge and their loss. Righteous persons have knowledge and memory as a result of virtuous deeds. Sinful persons have loss of memory and knowledge as a result of vicious deeds. Virtue promotes peace and hence intellectual powers.Apohanam Loss (destruction or absence) of memory and knowledge, as also of the reasoning faculty. The loss of memory and knowledge is due to lust, anger, grief and delusion.Smriti Memory. It is a special modification of the mind (Antahkarana Vritti) born of the Samskaras that causes the revival of the past experiences or enjoyments of sensual objects of this life in a worldy man who has not practised Yoga. A Yogi gets revival of experiences of his past lives and transcendental knowledge that is beyond time, space and causation and visible nature.I am the central topic of the Vedas. To understand the Vedas is to Know Me. I, the Supreme Being, am to be known in all the Vedas. It is I Who know the Vedic teaching or the meaning of the Vedas. I cause the teaching of the Vedanta to be handed down in regular succession
