So how to drop from the mind to the inner point of the heart? Use sound, intone sound. One sound will be helpful. If there are many sounds in the mind, it is difficult to leave them. If there is only one sound, it can be left easily. So first many sounds are to be sacrificed for one sound. That is the use of concentration.
Intone one sound. Go on intoning it, first audibly so that you can hear it, and then by and by, slowly, inaudibly. No one else can hear it then, but you can hear it inside. Make it more quiet, make it less and less audible, and then suddenly drop it. There will be silence, an explosion of silence - but feeling will be there. Now there will be no thought, but feeling will be there.
