BG 13.26
यावत्संजायते किंचित्सत्त्वं स्थावरजङ्गमम्
क्षेत्रक्षेत्रज्ञसंयोगात्तद्विद्धि भरतर्षभ
yāvatsaṃjāyate kiṃcitsattvaṃ sthāvarajaṅgamam
kṣetrakṣetrajñasaṃyogāttadviddhi bharatarṣabha
TRANSLATION
Whatever being is born, whether it is moving or stationary, know, O Arjuna, that it is through the combination of the Kshetra (body) and Kshetrajña (knower of the Field).
PURPORT
Whatever being is born, whether it be movable or stationary, it is born only from the mutual combination of the Kshetra and Kshetrajña. The sense is that it is born only from this combination, i.e., is born as a compound of the two and never in their separateness.
