Austerity

Anudvega-karam vakyam satyam priya-hitam cha yat, svadhyayabhyasanam chaiva van-mayam tapa ucyate

Speech that does not cause distress, is truthful, pleasant, beneficial, and includes the regular recitation of scriptures—this is said to be austerity of speech.

Acts of sacrifice, charity, and austerity should not be abandoned, but should indeed be performed, for sacrifice, charity, and austerity are purifying for the wise.
