Question: When I see myself cherishing indulgence and I start doubting my sincerity, what should I do?Sri Chinmoy: If you have real sincerity, sincerity will protect you. Sincerity itself has abundant power, but we underestimate the power of sincerity. If you think you are sincere to your goal when you make mistakes, at that time you are not being sincere. When sincerity is firm, you cannot make any mistake. Sincerity-power will negate temptation-power, and the result is that you will become more sincere. But when you do make a mistake, you should always try again. If you really have sincerity, your sincerity will appear a few minutes later to make you feel that the case is not totally lost. You have fallen; try to get up, walk, march, run again.
