देही नित्यमवध्योऽयं देहे सर्वस्य भारत।
तस्मात्सर्वाणि भूतानि न त्वं शोचितुमर्हसि।।2.30।।
।।2.30।।हे भरतवंशोद्भव अर्जुन सबके देहमें यह देही नित्य ही अवध्य है। इसलिये सम्पूर्ण प्राणियोंके लिये अर्थात् किसी भी प्राणीके लिये तुम्हें शोक नहीं करना चाहिये।
The eternal soul embodied within the physical body regardless whether it is a human earthly body or the physical bodies possessed by the demigods in the heavenly spheres; the immortal soul is eternally invulnerable even though the body perishes. Hence understanding this principle as fundamental whatever diversity and varieagatedness in the forms of bodies born from the womb of a female who was also conceived in the womb of a female that exists from the demigods down through the human species as well as to the animal species and the fish species and even including the immovable plants and trees it should be clearly understood that equanimity prevails regarding the essential nature of the immortal soul abiding therein whatever the bodily form and is eternal. Whereas the physical body is transient. So Arjuna is being instructed that factually according to this proper understanding regarding all living entities, he has no basis to lament for any being.
