सर्वस्य चाहं हृदि सन्निविष्टो
मत्तः स्मृतिर्ज्ञानमपोहनं च।
वेदैश्च सर्वैरहमेव वेद्यो
वेदान्तकृद्वेदविदेव चाहम्।।15.15।।
।।15.15।।मैं सम्पूर्ण प्राणियोंके हृदयमें स्थित हूँ। मेरेसे ही स्मृति? ज्ञान और अपोहन (संशय आदि दोषोंका नाश) होता है। सम्पूर्ण वेदोंके द्वारा मैं ही जाननेयोग्य हूँ। वेदोंके तत्त्वका निर्णय करनेवाला और वेदोंको जाननेवाला भी मैं ही हूँ।
Lord Krishnas manifestation of Himself as paramatma the Supreme Soul situated within the etheric heart of every jiva or embodied being next to His expansion of the atma or individual immortal soul. The heart is the exclusive, absolute center from where all consciousness radiates. It is also the factual center from where all impulses and frequencies originate both active and passive. The Brihadaranya Upanisad V.VI.I beginning manomayo ayam puruso states: One meditating should perceive the resplendent Supreme Lord the ruler and lord of all within the heart of the size of a grain of rice. The Chandogya Upanisad VIII.I beginning harih sum atha yadidamasmin states: Within the jiva or embodied being in the inner sanctorum of the heart abides the atma or immortal soul which is an infintesimal portion of paramatma. Hence from the Supreme Lord comes all memory remembered from past experience. All wisdom accruring from factual true perception and inference. Intuitive knowledge related exclusively to the authority of the Vedic scriptures and meditation which expands the consciousness. Contrarily also from the Supreme Lord comes the antithesis of the above which are loss of memory, speculative reasoning, erroneous hypothesis, conjectural suppositions and deprivation of consciousness. The Supreme Lord is to be known by the exclusive authority of the Vedic scriptures. He is the atma within all jivas, the witness, the monitor, the inner guide. The terms found in the Vedas of demigod, humans, demons, etc. are alluding to the jivatma or individual immortal soul within the myriad of varieagated forms of embodied beings. The compound word vedanta-krt refers directly to Lord Krishnas avatara or incarnation of Vedavyasa who compiled the Vedas and divided them into four divisions. It also denotes the performance of Vedic enjoined rituals. The antonym antah also means the end which infers the fruits, the results of such rituals. He is the sole bequeather of all the fruits promised in the Vedic scriptures. This was previously touched upon in chapter seven verses 21 and 22 where Lord krishna confirms that in whatever form one chooses to worship the Supreme Lord, He renders there faith firm and they obtain the wishes they yearned for from Him alone. He is also the supreme knower of the Vedic scriptures for they originated from Him to guide and teach jivas about Himself. Whosoever understands the Vedic scriptures otherwise then what has been instructed by Lord Krishna in Srimad Bhagavad-Gita factually has no knowledge of it at all. This is due to their understanding and comprehension being influenced by under faulty assumptions and erroneous suppositions. The Vedic scriptures must be understood exclusively in light of the comprehensive and full authority of the Bhagavad-Gita.
