There are many phases of spiritual knowledge and transcendental bliss. On one platform are the ritualistic sacrifices recommended in the Vedas, the execution of austerities and pious duties, and the practice of mystic yoga. These all reward different results to their performer. The rewards of these practices, however, appear to be very glittering as long as one is not elevated to the transcendental loving service of the Lord. Love of God is dormant in everyone, and it can be awakened from its dormant position by the execution of pure devotional service, just as a person bitten by a serpent can be awakened by ammonia.
After speaking in this way about devotional service, Lord Caitanya begins to describe devotional service and its symptoms to Rūpa Gosvāmī. He explains that in pure devotional service there can be no desire other than the desire to advance in Kṛṣṇa consciousness. In Kṛṣṇa consciousness there is no scope for worshiping any demigod or any other form of Kṛṣṇa, nor is there room for indulgence in speculative empiric philosophy, nor indulgence in fruitive activities. One should be free from all these contaminations. A devotee should accept only those things that are favorable to keep his body and soul together and should reject those things that increase the demands of the body. Only the bare necessities for bodily maintenance should be accepted. By minimizing bodily necessities, one can primarily devote his time to the cultivation of Kṛṣṇa consciousness through the chanting of the holy names of God. Pure devotional service means engaging all the senses of the body in the service of the Lord. At the present moment, our senses are all designated because the body is designated. Consequently we think that this body belongs to a particular society or a particular country or a particular family. In this way the body is bound by so many designations. Similarly, the senses belong to the body, and when the body is subject to such designations, the senses are also. Thus the senses engage themselves on behalf of family, society, nation and so on. When they are so engaged, they cannot cultivate Kṛṣṇa consciousness. The senses must be purified, and this is possible when one purely understands that he belongs to Kṛṣṇa and that his life belongs to Kṛṣṇa. The devotee should see his identity as an eternal servant of Kṛṣṇa. In this way one can engage his senses in the service of the Lord. Such engagement is called pure devotional service.
A pure devotee accepts the transcendental loving service of the Lord but rejects all kinds of liberation for his personal sense gratification. In Śrīmad-Bhāgavatam (3.29.11-13) Lord Kapila explains that as soon as a pure devotee hears the glories and transcendental qualities of the Supreme Personality of Godhead, who is seated in everyone's heart, his mind immediately flows toward the Lord, just as the waters of the Ganges flow toward the sea. Such spontaneous attraction to the service of the Supreme Personality of Godhead is most important to pure devotional service. Devotional service is pure when one engages in the service of the Supreme Lord without any motive and without being hampered with material impediments. The pure devotee does not desire to live on the same planet with the Supreme Lord, nor does he desire the same opulence as the Lord, nor does he desire to have the same form as the Lord, nor to live with Him side by side, nor to merge into His existence, etc. Even if the devotee were offered such rewards by the Lord, he would reject them. The point is that a devotee is so much absorbed in the transcendental loving service of the Lord that he has no time to think of any benefit beyond his immediate engagement. Just as an ordinary materialistic businessman thinks of nothing else when he is absorbed in his business, a pure devotee, when engaged in the service of the Lord, does not think of anything beyond that engagement.
If one is so absorbed in the rendering of service, he can be understood to be elevated to the highest position of bhakti. By such transcendental loving service alone can one surpass the influence of māyā and relish pure love of Godhead. As long as one desires material benefit or liberation, which are called the two witches of allurement, he cannot relish the taste of transcendental loving service to the Supreme Lord.
There are three stages of devotional service: The first is the beginning stage of cultivation, the second is the realization of service, and the third, the supreme stage, is the attainment of love of Godhead. There are nine different methods of cultivating devotional service—such as hearing, chanting, remembering, etc.—and all these processes are employed in the first stage. If one is engaged in chanting and hearing with devotion and faith, his material misgivings gradually become vanquished. As his faith in devotional service gradually increases, he becomes assured of a higher perfectional position. In this way one can become firmly fixed in devotion, increase his taste for it, become attached and feel ecstasy. This ecstasy occurs in the preliminary stage of love of Godhead. Attainment of ecstasy is produced by execution of devotional service. When one continues the process of hearing and chanting, attachment grows and assumes the name of love of Godhead.
