Unless we change the habit pattern of the deepest level of the mind, all other things thtat we are doing at the surface are only temporary; they cannot help.... so you must go to that root. If you don't make the whole journey from the surface level of your mind to the depth of your mind, how can you change your mind at the depth level? That requires something like a surgical operation of the mind—and that requires proper guidance, a proper environment, and some time. You don't just sit down, meditate and immediately penetrate to the depth; it's not possible. You have to go layer by layer, layer by layer, and reach the place where the deep, unconscious mind is blindly reacting, all the time reacting: anger, hatred, anger, hatred, craving, clinging. These are the habit patterns. You have to reach that stage, and it takes time. - S. N. Goenka, from “Meditation Now”
