Because the Creator of the men as well as of the world who is familiar with the special creation of human beings knows his path of perfection and salvation and therefore, accordingly has revealed it to the Holy Prophet (S) through the revelations so that he may present it to the people for their utilization.
This is the only way and all other ways are deviated and misleading and will never take a wayfarer to his final destination. A wayfarer must be absolutely obedient to religious law and for his mystical journey should not follow any other path except the religious path and should avoid strictly engaging into invocations and incantations that do not have any authenticity in religious law.
Because, not only they do not take a wayfarer towards his destination instead, carry him farther apart from his destination since deviation from religious law is innovation and sin.
To start with, a wayfarer should try his best to perform all religious obligatory obligations correctly in accordance with regulations, because, their renunciation will not result in attainment of higher spiritual positions, however seriously he may endeavor in performing recommended deeds and engaging into invocations and incantations. During the second stage the recommended deeds and invocations might be included in the program.
The wayfarer at this stage in accordance to his spiritual strength and personal capabilities may perform recommended deeds and the more he endeavors the greater will be the possibilities of his attaining higher spiritual positions.
From the point of view of superiority, it should be pointed out that all recommended deeds are not equal rather some of them excel over others and with the result some of them could be more better and favorite, as have been mentioned in the books of supplication and traditions. A wayfarer might select some supplications, prayers, invocations, and incantations from these books and then may engage himself on a regular basis.
