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.
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.
Lord Chaitanya, however, has recommended only one yajna, or sacrifice, called the sankirtana-yajna, the chanting of Hare Krishna, in which everyone can take part. Thus both devotees and fruitive workers can derive equal benefit from the performances of sankirtana-yajna.
Purport on Srimad bhagavatam 1.16.20
In Jagannatha Puri Chaitanya Mahaprabhu’s only occupation was holding Sankirtana at least four hours every day and distributing prasadam to the devotees.
