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.

If a devotee is morose, that means he is meditating on sense gratification and not fully engaged in enthusiastically serving Sri Krishna.
