Brāhmaṇas should execute their regulative duties in worshiping Lord Viṣṇu. Those who are advanced in knowledge of religious principles must avoid five kinds of irreligion, known as vidharma, para-dharma, dharmābhāsa, upadharma and chala-dharma. One must act according to the religious principles that suit his constitutional position; it is not that everyone must adhere to the same type of religion. A general principle is that a poor man should not unnecessarily endeavor for economic development. One who refrains from such endeavors but who engages in devotional service is most auspicious.
