1 Gita Sloka Every Day - Chapter 13 - Kshetra Kshetrajna Yoga - Sloka 26
Yavat samyate kinchit satvam sthavara jangamam I
Kshetra kshetrajna samyogat tat viddhi bharat rishabha II sloka 26
यावत् सम्यते किञ्चित् सत्यं स्थावर जङ्गमं I
क्षेत्र क्षेत्रज्ञ संयोगात् तत् विद्धि भरत ऋषभ I I श्लोक 26
Whatever being is born, the unmoving or the moving, O best of the Bharatas, know it to be from the union of Kshetra and kshetrajna.
An analogy from the cinematograph facilitates the understanding of the relationship between kshetra and kshetrajna. The moving light and shadow projected on the stationary screen, produce the required effect. The picture of an active man is possible because of the combined contribution of the kinetic light and shadow and the static screen. A blazing fire is seen on the screen, which in fact remains unaffected. Parallel to this are the contributions made by the Kshetra and kshetrajna in producing the phenomenal universe and beings in it. The insentient khsetra appears to be sentient due to its being super-imposed on kshetrajna. The immovable kshetrajna in his turn appears to be born, grow and die, h the due to his identification with the kshetra. The man in ignorance misreads the characteristics of the kshetra in the kshetrajna and vice versa. It is knowledge to understand these two entities as they are in themselves, and not as they seem to be because of their mutual intermingling.
