Buddhism and Sufism

Buddha preached a practice of intense self effort, avoiding speculation. His teachings present a specific series of methods that help build a balanced, wholesome life and healthy mind by developing the two very important qualities of wisdom and compassion. In its simplest form, Buddhism instructs the individual to eliminate bad habits and develop skills to maintain good habits. As one practices this systematic training, one becomes more aware and more perceptive in understanding how to further develop skills, focus, and mental insight while looking into life, not just at it. Gradual yet continuous incremental improvements lead to even greater insight and a deeper and more thoughtful understanding of the cycle of life.

In the very beginning the Buddha taught that the disciple must examine even the Buddha himself so that he (the disciple) might be fully convinced of the true value of the teacher whom he followed. Likewise, the disciple should examine and test the teachings of the teacher in order to dispel doubt and understand and see clearly as he progresses.I think we are supposed to doubt, question and examine the Insan Kamil in the same way yet look to this person for guidance and practice.

Following a path or a side road may be interesting and even enlightening and help us understand that there may be a more direct methodology. I don't think blind faith is expected here any more than in Buddhism.
