Narada-bhakti-sutra (sutras 1 to 8 only)

Throughout the Bhagavad-gītā Lord Kṛṣṇa teaches that one should give up all other processes of self-realization and fully surrender unto Him. That is faith. One who has full faith in Kṛṣṇa (śraddhā) and surrenders unto Him is eligible for being raised to the level of prema, which Lord Caitanya taught as the highest perfectional stage of human life.

Narada Bhakti Sutra 2, Purport:

The first requirement is that one should have sufficient faith that the only process for attaining love of Godhead is bhakti, devotional service to the Lord. Throughout the Bhagavad-gītā Lord Kṛṣṇa teaches that one should give up all other processes of self-realization and fully surrender unto Him. That is faith. One who has full faith in Kṛṣṇa (śraddhā) and surrenders unto Him is eligible for being raised to the level of prema, which Lord Caitanya taught as the highest perfectional stage of human life.

Some persons are addicted to materially motivated religion, while others are addicted to economic development, sense gratification, or the idea of salvation from material existence. But prema, love of God, is above all these. This highest stage of love is above mundane religiosity, above economic development, above sense gratification, and above even liberation, or salvation. Thus love of God begins with the firm faith that one who engages in full devotional service has attained perfection in all these processes.

The next stage in the process of elevation to love of God is sādhu-saṅga (CC Madhya 22.83), association with persons already in the highest stage of love of God. One who avoids such association and simply engages in mental speculation or so-called meditation cannot be raised to the perfectional platform. But one who associates with pure devotees or an elevated devotional society goes to the next stage—bhajana-kriyā, or acceptance of the regulative principles of worshiping the Supreme Lord. One who associates with a pure devotee of the Lord naturally accepts that person as his spiritual master, and when the neophyte devotee accepts a pure devotee as his spiritual master, the duty of the spiritual master is to train the neophyte in the principles of regulated devotional service, or vaidhi-bhakti. At this stage the devotee's service is based on his capacity to serve the Lord. The expert spiritual master engages his followers in work that will gradually develop their consciousness of service to the Lord. Therefore the preliminary stage of understanding prema, love of God, is to approach a proper pure devotee, accept him as one's spiritual master, and execute regulated devotional service under his guidance.

The next stage is called anartha-nivṛtti, in which all the misgivings of material life are vanquished. A person gradually reaches this stage by regularly performing the primary principles of devotional service under the guidance of the spiritual master. There are many bad habits we acquire in the association of material contamination, chief of which are illicit sexual relationships, eating animal food, indulging in intoxication, and gambling. The first thing the expert spiritual master does when he engages his disciple in regulated devotional service is to instruct him to abstain from these four principles of sinful life.

Since God is supremely pure, one cannot rise to the highest perfectional stage of love of God without being purified. In the Bhagavad-gītā (10.12), when Arjuna accepted Kṛṣṇa as the Supreme Lord, he said, pavitraṁ paramaṁ bhavān: "You are the purest of the pure." The Lord is the purest, and thus anyone who wants to serve the Supreme Lord must also be pure. Unless a person is pure, he can neither understand what the Personality of Godhead is nor engage in His service in love, for devotional service, as stated before, begins from the point of self-realization, when all misgivings of materialistic life are vanquished.
