The path of devotional service of a pure devotee
SB Canto 1
The Lord vanquishes all obstacles on the path of devotional service of a pure devotee
SB 1.7.10, Purport: The word hari conveys various meanings, but the chief import of the word is that He (the Lord) vanquishes everything inauspicious and takes away the mind of the devotee by awarding pure transcendental love. By remembering the Lord in acute distress one can be free from all varieties of miseries and anxieties. Gradually the Lord vanquishes all obstacles on the path of devotional service of a pure devotee, and the result of nine devotional activities, such as hearing and chanting, becomes manifested.
The pure devotee does not render service unto the Lord for such exchange, and therefore the full mercy of the Lord is open for him
SB 1.8.29, Purport: Darkness and light are two opposite conceptions, but this does not mean that the sun is partial in distributing its rays. The sun rays are open to everyone, but the capacities of the receptacles differ. Foolish people think that devotional service is flattering the Lord to get special mercy. Factually the pure devotees who are engaged in the transcendental loving service of the Lord are not a mercantile community. A mercantile house renders service to someone in exchange for values. The pure devotee does not render service unto the Lord for such exchange, and therefore the full mercy of the Lord is open for him.
The Lord's pure devotee renders service unto the Lord out of unalloyed love only
SB 1.8.31, Purport: The Supreme Lord is the Supreme in all circumstances, as already explained. Here is a specific example of the Lord's being the Supreme and at the same time a plaything in the presence of His pure devotee. The Lord's pure devotee renders service unto the Lord out of unalloyed love only, and while discharging such devotional service the pure devotee forgets the position of the Supreme Lord. The Supreme Lord also accepts the loving service of His devotees more relishably when the service is rendered spontaneously out of pure affection, without anything of reverential admiration.
The only desire that a pure devotee entertains is that he may always be in rapt attention with thinking of the lotus feet of the Lord
SB 1.9.24, Purport: A pure devotee is never very anxious to go back to the kingdom of God. He entirely depends on the good will of the Lord. He is equally satisfied even if the Lord desires him to go to hell. The only desire that a pure devotee entertains is that he may always be in rapt attention with thinking of the lotus feet of the Lord, regardless. Bhīṣmadeva wanted this much only: that his mind be absorbed in thinking of the Lord and that he pass away thus. That is the highest ambition of a pure devotee.
SB Canto 3
No material condition can stop the flow of the devotional service of a pure devotee
SB 3.29.11-12, Purport: The flow of the Ganges water cannot be stopped by any condition; similarly, a pure devotee's attraction for the transcendental name, form and pastimes of the Supreme Godhead cannot be stopped by any material condition. The word avicchinnā, "without interruptions," is very important in this connection. No material condition can stop the flow of the devotional service of a pure devotee.
