Śrīla Rūpa Gosvāmī states that his elder brother (Sanātana Gosvāmī) has compiled Hari-bhakti-vilāsa for the guidance of the Vaiṣṇavas, and therein has mentioned many rules and regulations to be followed by the Vaiṣṇavas. Some of them are very important and prominent, and he will now mention these very important items for our benefit. The purport of this statement is that Śrīla Rūpa Gosvāmī proposes to mention only basic principles, not details. For example, a basic principle is that one has to accept a spiritual master. Exactly how one follows the instructions of his spiritual master is considered a detail. For example, if one is following the instruction of his spiritual master and that instruction is different from the instructions of another spiritual master, this is called detailed information. But the basic principle of acceptance of a spiritual master is good everywhere, although the details may be different. Śrīla Rūpa Gosvāmī does not wish to enter into details here, but he wants to place before us only the principles.
He mentions the basic principles as follows: 1) accepting the shelter of the lotus feet of a bona fide spiritual master, 2) becoming initiated by the spiritual master and learning how to discharge devotional service from him, 3) obeying the orders of the spiritual master with faith and devotion, 4) following in the footsteps of great ācāryas (teachers) under the direction of the spiritual master, 5) inquiring from the spiritual master how to advance in Kṛṣṇa consciousness, 6) being prepared to give up anything material for the satisfaction of the Supreme Personality of Godhead, Śrī Kṛṣṇa (This means that when we are engaged in the devotional service of Kṛṣṇa, we must be prepared to give up something which we may not like to give up, and also we have to accept something which we may not like to accept.), 7) residing in a sacred place of pilgrimage like Dvārakā or Vṛndāvana, 8) dealing with the material world only as far as necessary, 9) observing the fasting day on Ekādaśī, and 10) worshiping sacred trees like the banyan tree and others.
These ten items are preliminary necessities for beginning the discharge of devotional service in regulative principles. In the beginning, if a neophyte devotee observes the above-mentioned ten principles, surely he will quickly make good advancement in Kṛṣṇa consciousness.
The next set of instructions is listed as follows: 1) One should rigidly give up the company of nondevotees. 2) One should not instruct a person who is not desirous of accepting devotional service. 3) One should not be very enthusiastic about constructing costly temples or monasteries. 4) One should not try to read too many books, nor should one develop the idea of earning his livelihood by lecturing on or by professionally reciting Śrīmad-Bhāgavatam or the Bhagavad-gītā. 5) One should not be neglectful in ordinary dealings. 6) One should not be under the spell of lamentation in loss or tribulation in gain. 7) One should not disrespect the demigods. 8) One should not give unnecessary trouble to any living entity. 9) One should carefully avoid the various offenses in chanting the holy name of the Lord, or in worshiping the Deity in the temple. 10) One should be very intolerant towards the blasphemy of the Supreme Personality of Godhead, Kṛṣṇa, or His devotees.
