Gopis dedicated their bodies and everything else they possesed to Krsna

CC Ādi 4.181 — Now, whatever affection we see the gopīs show for their own bodies, know it for certain to be only for the sake of Lord Kṛṣṇa.

CC Ādi 4.182 — [The gopīs think:] “I have offered this body to Lord Kṛṣṇa. He is its owner, and it brings Him enjoyment.

CC Ādi 4.183 — “Kṛṣṇa finds joy in seeing and touching this body.” It is for this reason that they cleanse and decorate their bodies.

CC Ādi 4.184 — “O Arjuna, there are no greater receptacles of deep love for Me than the gopīs, who cleanse and decorate their bodies because they consider them Mine.”

 

At our level, we can consider using our bodies totally in Krishna's service and in sharing Lord Caitanya's movement with others. Taking care of our health, cleanliness, exercise  etc because it is Krishna's body so it can be used in His service for His pleasure.

 

Sicne this body is meant for Krishna's pleasure sleeping too much, relaxing too much, wasting time on electronic gadgets and using the body for sense gratification is inappropriate.
