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.
When one attains the third stage of transcendental love of God, there occur further developments known as transcendental affection, emotion, ecstasy, and extreme and intense attachment. These are technically known by the terms rāga, anurāga, bhāva and mahābhāva. The progress from one stage to another can be compared to the thickening of sugar candy juice. In the first stage sugar candy juice is like a thin liquid. When, by evaporation, it becomes thicker and thicker, it turns into molasses. Finally it turns into granules and becomes sugar, rock candy and so on. Just as liquid sugar juice progresses from one stage to another, similarly transcendental love for the Supreme Lord develops by stages.
When one actually becomes situated on the transcendental platform, he becomes steady. Unless one is so situated, his position may not be steady and he may fall down. When one is actually situated transcendentally, there is no fear of falling down. This stage of understanding is technically called sthāyi-bhāva. There are even stages beyond this position, and they are known as vibhāva, anubhava, sāttvika and vyabhicārī. After one attains these, there is actually an exchange of rasa, or transcendental activity with the Supreme Lord. This exchange in loving reciprocation between the lover and the beloved is generally called kṛṣṇa-bhakti-rasa. It should be noted that the transcendental loving exchanges stand on the steadfast position of sthāyi-bhāva, as explained before. The basic principle of vibhāva is sthāyi-bhāva, and all other activities are auxiliary for the development of transcendental love.
