Detachment or non-attachment is the first important discipline that should be undertaken. The second is constant practice. What kind of
practice can be called constant? One kind is austerity or penance. The moment people hear this word austerity they get a little frightened.
They inevitably associate austerity with going into the forest, eating whatever fruits and roots are available there and exposing themselves
to all kinds of risks and sufferings. Truly speaking, that is not austerity; that is just putting the body through some suffering and punishment.
It is not the body that must undergo the suffering, but the mind. The mind tends towards either sloth and chaos or endless activity, and is
filled with the sense of doership and possessiveness. Austerity is putting such a mind with all these negative tendencies that cling to
it, through real torture, until all these tendencies let go their hold. Austerity also means removing the defects that are inherent in
the sense organs. This is the real austerity. There are three types of austerity. One is the physical austerity of the body, the second one
is the vocal austerity of the tongue and the third is mental austerity of the mind.
