Exposing myself to heat and cold and disregarding hunger and thirst, I shall reduce my body by performing most difficult asceticism. I shall live on fruits, ripe or unripe; I shall be in contemplation; I shall worship the Pitris and the celestial with speech and with the fruit of the forest.
शीतवातातपसहः क्षुत्पिपासानवेक्षकः। तपसा दुश्चरेणेदं शरीरमुपशोषयन्॥ एकान्तशीली विमृशन् पक्वापक्वेन वर्तयन्। पितॄन् देवांश्च वन्येन वाग्भिरद्धिश्च तर्पयन्।३५॥
