" Hammered into the Heart
In the Sufi tradition light and knowledge are reflected from heart to heart. The heart is the organ of the higher consciousness — the consciousness of the Self. Spiritual teachings can be reflected or impressed directly into the heart, bypassing the limitations of the mind. . . . A further part of the Sufi training is to bring the mind into the heart, the mind 'hammered into the heart' as the Sufis say, so that the teachings given to the heart can be assimilated into everyday consciousness. A mind that has been brought into the heart can understand the ways of oneness, which are often paradoxical, sometimes even nonsensical, to the rational self. "
