Translation:
Disregarding the ridicule of one’s companions, one should give up the bodily conception and its accompanying embarrassment. One should offer obeisances before all — even the dogs, outcastes, cows and asses — falling flat upon the ground like a rod.
Purport:
One should practice seeing the Supreme Personality of Godhead within all creatures. Sri Caitanya Mahaprabhu advised all devotees to consider themselves lower than a blade of grass and to be more tolerant than a tree. In such a humble position, one will not be disturbed in the prosecution of pure devotional service to the Lord. A devotee does not foolishly think that a cow or an ass is God, but rather the devotee sees the Supreme Lord within all creatures, and on this higher, spiritual plane he does not discriminate.
