देही नित्यमवध्योऽयं देहे सर्वस्य भारत
तस्मात्सर्वाणि भूतानि न त्वं शोचितुमर्हसि
dehī nityamavadhyo'yaṃ dehe sarvasya bhārata
tasmātsarvāṇi bhūtāni na tvaṃ śocitumarhasi
TRANSLATION
The self in the body, O Arjuna, is eternal and indestructible. This is so in the case of the selves in all bodies. Therefore, it is not fit for you to feel grief for any being.
PURPORT
The self within the body of everyone such as gods etc., must be considered to be eternally imperishable, though the body can be killed. Therefore, all beings from gods to immovable beings, even though they possess different forms, are all uniform and eternal in their nature as described above. The inequality and the perishableness pertain only to the bodies. Therefore, it is not fit for you to feel grief for any of the beings beginning from gods etc., and not merely for Bhishma and such others.
