Lord Caitanya Mahāprabhu says that, "I accept the order of My spiritual master in toto, without any interpretation, without any argument, without any understanding. Whatever he has said, it is all right." This is acceptance of spiritual master. "Oh, I accept spiritual master, but I don't accept your order"—this is not acceptance of spiritual master. If you at all accept somebody as spiritual master, you must test him. You must test him for at least one year if you have got doubts. And when you are convinced that, "Here is a person whom I can follow blindly," then you accept.
You haven't got to follow blindly. Spiritual master will not place before you anything unreasonable. But the process is that you cannot change the order of spiritual master. You cannot argue. He . . . unless you are convinced that, "I shall accept the order of this person without any argument," don't accept anybody as spiritual master. It is a false acceptance. Just see. Caitanya Mahāprabhu says that.
And other point is that if you take Caitanya Mahāprabhu's life, oh, He was a vast learned scholar, but He said that His spiritual master found Him the nonsense. Now how it is that? He was a great scholar, and how His spiritual master found Him a nonsense? So therefore, however you may be a great scholar, if your spiritual master finds you a fool, you must accept that you are a fool.
