|Chapter 2: Contents of the Gita Summarized|
antavanta ime deha
tasmad yudhyasva bharata
The material body of the indestructible, immeasurable and eternal living entity is sure to come to an end; therefore, fight, O descendant of Bharata.
In this verse Krishna further explains the first point He made in Verse 2.16 – that the material body and all material situations are temporary and have no actual existence. Material bodies are sure to perish – they may perish immediately (as for certain type of insects that live for just a few seconds) or after a very long time (as for Lord Brahma who live for several trillion of our years). In either case the bodies eventually perish – it's just a matter of time. This verse reverses Arjuna's arguments based on compassion, that by not fighting he will save his family members from harm. The material body of each and every one of these family members will certainly come to an end, while their souls will remain eternally. Srila Prabhupada writes, "So from both viewpoints there is no cause of lamentation, because the living entity as he is cannot be killed nor can the material body be saved for any length of time or permanently protected."
