Whenever one commits immoral acts like theft, violence, adultery, deception, he/she has a queer feeling of uneasiness with in. His/her limbs start shaking and pulse- rate becomes irregular. It is nothing but an adverse reaction of the higher self (Soul) to an immoral act or behaviour of the lower animal self.
Immorality is contrary to the nature and interests of the Soul. On the other hand, virtuous acts involving altruism, philanthropy, kindheartedness, self-sacrifice and continence provide great inner satisfaction, lightheartedness, cheerfulness and exhilaration.
Only those persons who are able to listen to the promptings of the Soul (conscience) and act accordingly, are righteous and noble. Having risen above animal drives, a person tuned to the voice of conscience can never commit a sinful or evil act.
