Material compassion, lamentation and tears are all signs of ignorance of the real self. Compassion for the eternal soul is self-realization. The word “Madhusudana” is significant in this verse. Lord Krishna killed the demon Madhu, and now Arjuna wanted Krishna to kill the demon of misunderstanding that had overtaken him in the discharge of his duty. No one knows where compassion should be applied. Compassion for the dress of a drowning man is senseless. A man fallen in the ocean of nescience cannot be saved simply by rescuing his outward dress — the gross material body. One who does not know this and laments for the outward dress is called a sudra, or one who laments unnecessarily. Arjuna was a kshatriya, and this conduct was not expected from him. Lord Krishna, however, can dissipate the lamentation of the ignorant man, and for this purpose the Bhagavad-gita was sung by Him. This chapter instructs us in self-realization by an analytical study of the material body and the spirit soul, as explained by the supreme authority, Lord Sri Krishna. This realization is possible when one works without attachment to fruitive results and is situated in the fixed conception of the real self
When there is an epidemic disease, an antiseptic vaccine protects a person from the attack of such an epidemic. Similarly, food offered to Lord Vishnu and then taken by us makes us sufficiently resistant to material affection, and one who is accustomed to this practice is called a devotee of the Lord. Therefore, a person in Krishna consciousness, who eats only food offered to Krishna, can counteract all reactions of past material infections, which are impediments to the progress of self-realization.
He is a miserly man who does not solve the problems of life as a human and who thus quits this world like the cats and dogs, without understanding the science of self-realization.
A cruel proprietor of an animal sometimes kills the animal in his possession, yet the animal does not protest. Nor does it have any real independence. A Krishna conscious person, fully engaged in self-realization, has very little time to falsely possess any material object. For maintaining body and soul, he does not require unfair means of accumulating money. He does not, therefore, become contaminated by such material sins. He is free from all reactions to his actions.
