The Bhagavad Gita says that one who laughs is Narayana and one who cries is Nara. When Nara, represented by Arjuna was crying in a despondent mood, Narayana, represented by Krishna was at ease, even on the battlefield. We laugh only when we are happy. When we are happy, we not only laugh but also try to sing some songs. Those who have a sweet voice will sing in public. Those who do not have a sweet voice, will at least sing in the bathroom.
Krishna had a sweet voice and perfect knowledge of Raga and Tala and so he was singing the Gita even on the battlefield. The word Gita means song and amidst many difficulties on the battlefield, it is only a Krishna who can sing. This shows that God is the embodiment of happiness. Everyone of You must keep your mind and body in good condition. You should use your body for the sake of establishing truth and righteousness in the country. You must remember that Indian culture of which you are the custodians, should be re- established by you. >From Swami's Discourse in Brindavan in May'1973 Om Sai Ram
