Translation

BG 17.18: Austerity that is performed with ostentation for the sake of gaining honor, respect, and adoration is in the mode of passion. Its benefits are unstable and transitory.

Commentary

Although austerity is a powerful tool for the purification of the self, not everyone utilizes it with pure intention. A politician labors rigorously to give many lectures a day, which is also a form of austerity, but the purpose is to gain a post and prestige. Similarly, if one engages in spiritual activities to achieve honor and adulation, then the motive is equally material though the means is different. An austerity is classified in the mode of passion if it is performed for the sake of gaining respect, power, or other material rewards.
