Nobody should think himself that he is very prestigious person, falsely. Nobody is prestigious. Everyone should be humble. So these three, four things we should learn, and that is tapasya. And we should avoid the sinful activities, namely, no illicit sex, no meat-eating, no gambling, no intoxication. These are some of the positive and negative formulas given by Caitanya Mahāprabhu. And if we follow this tapasya and chant Hare Kṛṣṇa, then our life is successful.
Life is successful means it is stated here, sattvaṁ śuddhyed yasmād brahma-saukhyaṁ tv anantam (SB 5.5.1). We are, every one of us, we are after happiness, sukham. From sukham it has come saukhyam. That happiness, if we want to continue our eternal life, then we require eternal happiness. Without happiness our life is not worth. Ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12). Everyone should be happy, ānandamaya. That is spiritual world.
