Great sages, filled with magnificent sympathy for their fellowmen, laid down rules, regulations, limits, and directions for daily life and conduct, so that man’s hand and brain, his instincts and impulses, may not turn against man, but may turn towards the ideals of Satya, Dharma, Shanti, and Prema (Truth, Righteousness, Peace and Love). They declared that every karma or action must be weighed in the balance and approved only if it cleanses the emotions and passions; it has to be cast aside if it curdles or fouls them. Bhavashuddhi (purification of mental disposition) was the fruit of karma, and any act that befogs the bhava (thought process) or excites it into rajas (passion) or demeans it into tamas (inertia) has to be avoided. Yajnas and yagas (sacrificial rites and sacrificial offerings) were prescribed so that man may learn the glory of renunciation, not the glitter of pomp and conspicuous waste. Yajnas imposed on the performer and participants a rigorous routine of physical and mental cleanliness that led them on to the presence of the Supreme.
