Hari OM! In this chapter Lord Krishna clarifies what He has already revealed in the seventh chapter. Sovereign wisdom is primal wisdom. The word pratyaksavagaman is that which is experienced by direct realization of the brahman or spiritual substratum pervading all existence. That which is established in each of the sense organs individually is known as pratyaksa. The Moksa Dharma states: That which is established in the breath is different from the primal breath of the presiding deity. The presiding deity will not know him but he is like the body of the Supreme Lord. Similarly are the presiding deity of speech and the presiding deity of sight etc. The Supreme Purusa or supreme personality who is the size of a thumb is abiding in the etheric space within the heart. He is also established in the mind, the moon, space, the sun, etc. In the Vavravya section of the Sama Veda is stated: Having established each of the presiding deities as the perceiver of the sense organs, the Purusa being the archetype of the senses is also known as pratyaksa. One who understands the Purusa as such is endowed with wisdom. The word dharmyam means eternal righteousness and is representative of the Supreme Lord. All his activities are always established in eternal righteousness. Whatever is spoken about Him or written about Him from the Vedic scriptures concerning Him or any of authorized avatars or incarnations and His and their activities are always without exception established in eternal righteousness. He maintains and sustains the entire material creation therefore He is the foundation of dharma. Being the sole upholder of all dharma the Supreme Lord is revered as the apex and ultimate personality. Preserving and supporting all existence thereby all beings in creation are supported as well. The Sama Veda reveals: In the beginning only the Supreme Lord as dharma existed, neither the Earth, the wind or space, nor Brahma, nor Shiva, nor the demigods, nor the sages. The word pratyaksavagaman also denotes one of the ways to experience supernatural reality. Now begins the summation. What Lord Krishna stated in chapter seven is being explained in more detail here.
