Of all spiritual practices: meditation on the sayings of the Prophet and on the traditions of Sufism, meditated recitation of the Qoran, ritual Prayer, and so forth, the dhikr is the practice most apt to free spiritual energy, that is, to allow the particle of divine light which is in the mystic to rejoin its like.
The advantage of the dhikr is that it is not restricted to any ritual hour; its only limitation is the personal capacity of the mystic. It is impossible to study the question of colored aphorisms without knowing the spiritual exercise which is their source. Everything takes place, needless to say, in the ghayba, the suprasensory world; what is in question here is solely the physiology of the man of light.
Najm Kobra set himself the task of describing the cases and circumstances in which the fire of the dhikr itself becomes the object of mystical apperception. As opposed to the fire of the Devil, which is a dark fire, the vision of which is accompanied by distress and a feeling of overwhelming oppression, the fire of the dhikr is visualized as a pure and ardent blaze, animated by a rapid upward movement.
