“These are the general principles to be followed by all human beings: truthfulness, mercy, austerity (observing fasts on certain days of the month), bathing twice a day, tolerance, discrimination between right and wrong, control of the mind, control of the senses, nonviolence, celibacy, charity, reading of scripture, simplicity, satisfaction, rendering service to saintly persons, gradually taking leave of unnecessary engagements, observing the futility of the unnecessary activities of human society, remaining silent and grave and avoiding unnecessary talk, considering whether one is the body or the soul, distributing food equally to all living entities (both men and animals), seeing every soul (especially in the human form) as a part of the Supreme Lord, hearing about the activities and instructions given by the Supreme Personality of Godhead (who is the shelter of the saintly persons), chanting about these activities and instructions, always remembering these activities and instructions, trying to render service, performing worship, offering obeisances, becoming a servant, becoming a friend, and surrendering one’s whole self. O King Yudhisthira, these thirty qualifications must be acquired in the human form of life. Simply by acquiring these qualifications, one can satisfy the Supreme Personality of Godhead.
In order that human beings be distinct from the animals, the great saint Narada recommends that every human being be educated in terms of the above-mentioned thirty qualifications. Nowadays there is propaganda everywhere, all over the world, for a secular state, a state interested only in mundane activities. But if the citizens of the state are not educated in the above-mentioned good qualities, how can there be happiness? For example, if the total populace is untruthful, how can the state be happy? Therefore, without consideration of one’s belonging to a sectarian religion, whether Hindu, Muslim, Christian, Buddhist or any other sect, everyone should be taught to become truthful. Similarly, everyone should be taught to be merciful, and everyone should observe fasting on certain days of the month. Everyone should bathe twice a day, cleanse his teeth and body externally, and cleanse his mind internally by remembering the holy name of the Lord. The Lord is one, whether one is Hindu, Muslim or Christian. Therefore, one should chant the holy name of the Lord, regardless of differences in linguistic pronunciation. Also, everyone should be taught to be very careful not to discharge semen unnecessarily. This is very important for all human beings. If semen is not discharged unnecessarily, one becomes extremely strong in memory, determination, activity and the vitality of one’s bodily energy. Everyone should also be taught to be simple in thought and feeling and satisfied in body and mind. These are the general qualifications of a human being. There is no question of a secular state or an ecclesiastical state. Unless one is educated in the above-mentioned thirty qualities, there cannot be any peace. ”
