A devotee is always joyful

…a devotee does not attach much importance to the pains and trouble
pertaining to the body because he knows perfectly well that he is not the
material body. He does not identify with the body; therefore he is freed
from the conception of false ego and is equipoised in happiness and
distress. He is tolerant, and he is satisfied with whatever comes by the
grace of the Supreme Lord. He does not endeavor much to achieve something
with great difficulty; therefore he is always joyful.
