In the Hindu religion, all spiritual practices are started by uttering the word “AUM” (OM). Those who are sincere about seeking absolute freedom will also concentrate on the meaning of the word “TAT” (pure existence) when performing various religious rites or austerities so that no thought of personal gain enters their minds. The absolute reality behind all creation is known as “SAT” and it designates pure goodness. That word is uttered to remind the devotee that all his or her actions have their basis in the ultimate supreme divine and should be done to serve God. AUM-TAT-SAT is considered to be the designation for everything that is. Any actions undertaken without this in mind are considered worthless because they are ASAT (untrue).
