The renunciation of acts and humility form the highest penance. It is superior to all kinds of penance. He who performs such penance is considered as one who is always fasting and who is always leading a life of Brahmacharrya.
त्यागश्च संनतिश्चैव शिष्यते तप उत्तमम्। सदोपवासी च भवेद् ब्रह्मचारी सदा भवेत्॥
