How can the devotees really have any caste? Children are all equal.
Many think of God only after receiving blows from the world. But blessed indeed is he who can offer his mind, like a fresh flower, at the feet of the Lord from his very childhood. One should practice renunciation in youth.
As one gets the fragrance of a flower by handling it, or as one gets the smell of sandalwood by rubbing it against a stone, in the same way one gets spiritual awakening by constantly thinking of God. But you can realize Him right now, if you become desireless.
Only through work can one remove the bondage of work. Total detachment comes later. One should not be without work even for a moment. Work helps one to fend off idle thoughts.
Holy Mother Sarada Devi (1853-1920)
