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.
A devotee should be simple and clean dressed, but more than dress, the mind should be clean.
Krishna and pure devotees see through the substance, not the maya the world sees through.
If an ordinary man does not eat, he will grow weak and die. Similarly, if a devotee does not taste the transcendental pastimes of Lord Chaitanya Mahaprabhu and Lord Krishna, he will gradually weaken and die spiritually.
It is the aspiration of a devotee that while he chants the Hare Krsna maha-mantra his eyes will fill with tears, his voice falter and his heart throb. These are good signs in chanting the holy name of the Lord.
