Here is an answer that Seyyidina Ahmed Tidjani (may ALLAH sanctify his precious secret) sent to Sidi Hajj ‘Ali Harazim (may ALLAH be pleased with him) at the beginning of his spiritual journey with him
« In the name of Allah, the Beneficent, the Merciful. May ALLAH pray upon our Master Muhammad, his family, his companions and greet them. May the peace be upon you
You have mentioned the great efforts that you make and that are necessary in order to achieve your aim, to accomplish good deeds for the hereafter. This is due to that part of your soul which is drawn to rest. It is absorbed in passion, because it had thought that it could attain the station of knowledge of ALLAH (The Glorified, The Exalted) effortlessly. Thus, it tends towards resting where it has been led by its passion. If it realized that its aim regarding knowledge of ALLAH, can only be obtained through the well-known efforts that the spiritual path requires and by renouncing (bad) habits, then it would certainly have met all its requirements. Indeed, It yearns for the object of its research, but imagines that it is possible to obtain it without struggle. Because of this, it does not make the required effort and does not renounce pleasure and passion.
For each obstacle, the appropriate measure should be applied. He who thinks he can face obstacles simply by his heart in its present state, without taking into account the proper rules does not know the divine principles. By thinking this way, he will reap only fatigue and nothing else. The example given for the obstacle is that of a cloud in the sky, and the example of the effort behind it is the sun. If the sky becomes clear, then the sun appears, but if the clouds remain then they represent an obstacle between it and us. It is not conceivable that clouds may remain in the sky and that the sun could appear at the same time. Think and meditate upon this, you will benefit from a great knowledge.
