But there is a difficulty, and this is that if he wants to test the teacher first, then there is no end to the testing. He can go from one teacher to another, from the earthly being to the heavenly being, testing everyone, and in the end what will he find? Imperfection. He is looking for it, and he will find it. Man is an imperfect being, a human being, a limited being. If he wants to find perfection in a limited being, he will always end by being disappointed whoever he meets, whether it is an angel or a human being. If he were simple enough to accept any teacher that came his way and said, "I will be your mureed," it would be easier, though this is perhaps not always practicable.
