Kshetra Kshetrajna Vibhaga Yoga
Krishna introduces a key philosophical distinction: the kshetra, or 'field' — the body and the whole of material nature, with all its changes — and the kshetrajna, the 'knower of the field,' the conscious self or witness that inhabits it. He identifies himself as the kshetrajna present in every field, in every being, and defines true knowledge not as scholarship but as a cluster of virtues — humility, integrity, non-violence, forgiveness, self-control, steadiness of mind, devotion — with everything opposed to these named as ignorance. In a passage echoing the Upanishads, he describes the Supreme as having hands and feet everywhere, eyes and heads and mouths everywhere, pervading and yet transcending all things, both far and near, both undivided and yet appearing divided among beings. The chapter closes with the claim that one who truly sees the same imperishable Lord equally present in every being — not diminished when the body perishes — has attained real vision, and by that vision does no harm to the self and reaches the highest state.
“Know me to be the knower of the field in all fields, Arjuna; and I consider knowledge of the field and its knower together to be true knowledge.”
“Humility, integrity, non-violence, forgiveness, uprightness, service to the teacher, purity, steadfastness, and self-control — this is declared to be knowledge; what is opposed to it is ignorance.”
“That Supreme has hands and feet everywhere, eyes, heads and mouths everywhere, and hears everything everywhere in the world; it exists enveloping all.”
“One who sees the Supreme Lord existing equally in all beings, imperishable within the perishable, truly sees.”
“Seeing the same Lord present equally everywhere, one does not harm the self by the self, and thus attains the highest goal.”
