Human birth is most sacred and rare (Jantunam nara janma durlabham). The word manava (human being) also means one who is sacred. Why do we resort to debasing such a sacred human being? People advocate several good and sacred things, but when it comes to practice, they back out. When a conflict arises between precept and practice, you must have the courage to stand up to the situation and make every effort to tread the sacred path. You will, in your day-to-day life, encounter several people with bad qualities and wrong behaviour. Do not join their company. Offer them a salutation (namaskar) and move away. You may ask, why we should offer salutations to evil people. We salute good people, so as to not lose their company. We also salute the evil people requesting they move away from us. We must join the company of good people, cultivate good qualities, and lead a good life, thus sanctifying this precious life.
