Suta Gosvami
Sri Krishna, the Personality of Godhead, who is the Paramatma [Supersoul] in everyone's heart and the benefactor of the truthful devotee, cleanses desire for material enjoyment from the heart of the devotee who has developed the urge to hear His messages, which are in themselves virtuous when properly heard and chanted.
Lord Chaitanya
The devotee should be more tolerant than the tree and more submissive than the grass. He should offer all honour to others, but may not accept any honour for himself.
Lokanath Swami
A devotee should be simple and clean dressed, but more than dress, the mind should be clean.
Radhanath Swami
Krishna and pure devotees see through the substance, not the maya the world sees through.
A.C. Bhaktivedanta Swami Prabhupada
The Lord is careful about His devotee, just as a mother is always careful about her little child, who is completely dependent on her care.
Mukund Mala Stotra Verse 4
Srila Prabhupada
Srimad Bhagavatam
Devotees solely engaged in the devotional service of the Supreme Personality of Godhead, Narayana, never fear any condition of life. For them the heavenly planets, liberation and the hellish planets are all the same, for such devotees are interested only in the service of the Lord.
