He realizes that the people he about to fight are men just like him, some even worthy of his worship. He finds friends, relatives, cousins, and teachers amongst his enemy ranks. Love and respect for the elders touches his heart and the throws drown his bow and shield in despair. Being a warrior, he should fight the enemies. It is his duty, Krishna preaches Arjuna.
Man is mortal.
In death, his soul is immortal. The warrior throws away the body like old clothes. After death, the soul will take a new body. This is the most important chapter in the whole of Gita, advocating disciplined action for public good, which is named as Lokasangraha. Albert Schweitzer was delighted to find in this chapter, the very motive for public good which led him to serve lepers in Africa.
