Arjuna only had to become an instrument for Krsna (Chapter 1 Text 32-35)
- Hare Krishna Friends,
Chapter 1: Observing the Armies on the Battlefield of Kuruksetra
Everyone wants to show his opulence to friends and relatives, but Arjuna fears that all his relatives and friends will be killed in the battlefield, and he will be
unable to share his opulence after victory. This is a typical calculation of material life. The transcendental life is, however, different. Since a devotee wants to satisfy the desires of the Lord, he can, Lord willing, accept all kinds of opulence for the service of the Lord, and if the Lord is not willing, he should not accept a farthing.
Arjuna did not want to kill his relatives, and if there were any need to kill them, he desired that Krsna kill them personally. At this point he did not know that Krsna had already killed them before their coming into the battlefield and that he was only to become an instrument for Krsna. This fact is disclosed in the following chapters. As a natural devotee of the Lord, Arjuna did not like to retaliate against his miscreant cousins and brothers, but it was the Lord's plan that they should all be killed. The devotee of the Lord does not retaliate against the wrongdoer, but the Lord does not tolerate any mischief done to the devotee by the miscreants. The Lord can excuse a person on His own account, but He excuses no one who has done harm to His devotees. Therefore the Lord was determined to kill the miscreants, although Arjuna wanted to excuse them.
