The kind of mysticism is approved of which is based on the verses of the holy Quran, Ahadith, speeches and the traditions of Ahlulbayt (peace be upon them). Based on this type of mysticism, one is adorned with ethics and human virtues and avoids what is forbidden as well as the sins and the moral vices.
The ethics of the Ahlul-Bayt is based on virtue, as the main figures in this field were particularly pious. In this mysticism, love is for the truth and for the immortal source, but the mysticism which is based upon imagination of the mind and the dreams of others like the false mysticism such as the circle mysticism which never helps one's sublimity and improvement but makes one obsessed with imaginations and has no result but waste of time and life.
