निर्मत्सराय शुचये यस्याहं प्रेयसां प्रिय: ॥ ४२ ॥
yasyāhaṁ preyasāṁ priyaḥ
This instruction should be imparted by the spiritual master to persons who have taken the Supreme Personality of Godhead to be more dear than anything, who are not envious of anyone, who are perfectly cleansed and who have developed detachment for that which is outside the purview of Kṛṣṇa consciousness.
In the beginning, no one can be elevated to the highest stage of devotional service. Here bhakta means one who does not hesitate to accept the reformatory processes for becoming a bhakta. In order to become a devotee of the Lord, one has to accept a spiritual master and inquire from him about how to progress in devotional service. To serve a devotee, to chant the holy name according to a certain counting method, to worship the Deity, to hear Śrīmad-Bhāgavatam or Bhagavad-gītā from a realized person and to live in a sacred place where devotional service is not disturbed are the first out of sixty-four devotional activities for making progress in devotional service. One who has accepted these five chief activities is called a devotee.
One must be prepared to offer the necessary respect and honor to the spiritual master. He should not be unnecessarily envious of his Godbrothers. Rather, if a godbrother is more enlightened and advanced in Kṛṣṇa consciousness, one should accept him as almost equal to the spiritual master, and one should be happy to see such godbrothers advance in Kṛṣṇa consciousness. A devotee should always be very kind to the general public in instructing Kṛṣṇa consciousness because that is the only solution for getting out of the clutches of māyā. That is really humanitarian work, for it is the way to show mercy to other people who need it very badly. The word śuśrūṣābhiratāya indicates a person who faithfully engages in serving the spiritual master. One should give personal service and all kinds of comforts to the spiritual master. A devotee who does so is also a bona fide candidate for taking this instruction. The word bahir jāta-virāgāya means a person who has developed detachment from external and internal material propensities. Not only is he detached from activities which are not connected to Kṛṣṇa consciousness, but he should be internally averse to the material way of life. Such a person must be nonenvious and should think of the welfare of all living entities, not only of the human beings, but living entities other than human beings. The word śucaye means one who is cleansed both externally and internally. To become actually cleansed externally and internally, one should chant the holy name of the Lord, Hare Kṛṣṇa, or Viṣṇu, constantly.
The word dīyatām means that knowledge of Kṛṣṇa consciousness should be offered by the spiritual master. The spiritual master must not accept a disciple who is not qualified; he should not be professional and should not accept disciples for monetary gains. The bona fide spiritual master must see the bona fide qualities of a person whom he is going to initiate. An unworthy person should not be initiated. The spiritual master should train his disciple in such a way so that in the future only the Supreme Personality of Godhead will be the dearmost goal of his life.
In these two verses the qualities of a devotee are fully explained. One who has actually developed all the qualities listed in these verses is already elevated to the post of a devotee. If one has not developed all these qualities, he still has to fulfill these conditions in order to become a perfect devotee.
