The serenity of mind, gentleness, silence, self-restraint, and the purity of mind are called the austerity of thought.

Speech that is not offensive, truthful, pleasant, beneficial, and is used for the regular reading of scriptures is called the austerity of word.

I am the sweet fragrance in the earth. I am the heat in the fire, the life in all living beings, and the austerity in the ascetics.

Whatever you do, whatever you eat, whatever you offer as oblation to the sacred fire, whatever charity you give, whatever austerity you perform, do all that as an offering unto Me.
