Futility of mere physical acts:
NA KAMMUNA KAMMA KHAVENTI BAALA AKAMMUNA KAMMA KHAVENTI DHEERA
MEDHAAVINO LOBHAMAYAAVATEETA SANTOSINO NO PAKARENTI PAAVAM
the spirited savants shed their karmas with little effort;
the intelligent persons, who do not have greed and pride,
enjoy the virtue of contentment and do not obtain any demerit.
Mere physical activities do not help us to get rid of karma. These activities, which are performed without rational perception and rational knowledge, amount to childish penance (BAAL TAPAH). Jainism deprecates such religious activities. On the other hand, one, who has rational perception and rational knowledge, sheds one's karma without any physical activities. Moreover, an individual, who has no passions, and who practices equanimity, does not acquire demeritorious karma.
