Bhagavad Gita · Chapter 13: The Field and the Knower of the Field
Bhagavad Gita 13.26
यावत्सञ्जायते किञ्चित्सत्त्वं स्थावरजङ्गमम् ।
क्षेत्रक्षेत्रज्ञसंयोगात्तद्विद्धि भरतर्षभ ॥
yāvatsañjāyate kiñcitsattvaṃ sthāvarajaṅgamam | kṣetrakṣetrajñasaṃyogāttadviddhi bharatarṣabha ||
Whatever being comes into existence, moving or unmoving, know that it arises from the union of the field and the knower of the field, best of the Bharatas.
Modern context
Every living thing, from a tree to a person, arises from the union of the field and the knower, matter and awareness. Life is what happens when these two meet. A body without awareness is a corpse; awareness without a body has no way to act in the world. Each of us is a meeting point of the two, and seeing this clearly is the beginning of wisdom.
