Meher Baba wrote: “When the tongue is silent, the mind speaks; When the mind is silent, the heart sings; When the heart stops singing, Soul begins to experience its original Self. In deep sleep, tongue, mind and heart are silent. And one is unconscious. If one can go into deep sleep and remain awake, one has it; One becomes what one originally was and eternally is – God.”
