there is no happiness equal to contentment / there is no disease like covetousness / there is no virtue like mercy / shastra calls us to be cool headed / if we purify our existence by tapasya we can do wonderful things by the grace of the Lord / austerities for the body, words, and mind / our speech should be truthful, pleasing, beneficial, non-agitating / we all come in the achyuta-gotra - the family of Krishna
SB 6.4.47-50
