Commentary

Shree Krishna uses the words yāvat kiñchit, meaning “whatsoever form of life that exists,” regardless of how enormous or infinitesimal it may be, is all born of the union of the kṣhetrajña (knower of the field) and the kṣhetra (field of activities).  The Abrahamic traditions accept the existence of the soul in humans, but do not accept that other forms of life also have souls.  This concept condones violence toward the other life forms.  However, the Vedic philosophy stresses that wherever consciousness exists, there must be the presence of the soul.  Without it, there can be no consciousness.  

In the early twentieth century, Sir J.C. Bose established through experiments that even plants, which are non-moving life forms, can feel and respond to emotions.  His experiments proved that soothing music can enhance the growth of plants.  When a hunter shoots a bird sitting on a tree, the vibrations of the tree seem to indicate that it weeps for the bird.  And when a loving gardener enters the garden, the trees feel joyous.  The changes in the vibrations of the tree reveal that it also possesses consciousness and can experience semblances of emotions.  These observations corroborate Shree Krishna’s statement here that all life forms possess consciousness; they are the combination of the eternal soul, which is the source of consciousness, and the body, which is made of the insentient material energy.
