You are divine. Live up to it! Our frustration with our imperfections stems from our inherent perfection, and not from our supposed sinful nature. Our body and mind continually fluctuate and will continue to do so, as this is the nature of the body and mind. But we are not our body nor our mind. We are frustrated when we do not behave with dignity. So behave with dignity. This is sadhana. This is tapasya.
