Translation:
My dear Uddhava, general cleanliness, washing the hands, bathing, performing religious services at sunrise, noon and sunset, worshiping Me, visiting holy places, chanting japa, avoiding that which is untouchable, uneatable or not to be discussed, and remembering My existence within all living entities as the Supersoul — these principles should be followed by all members of society through regulation of the mind, words and body.
