Paul Brunton in his wonderful book describes this conversation with a true Yogi:
"This (Yoga path)is too serious to become the mere sport of a man’s leisure hours.”
I see my chances of becoming a Yogi fade swiftly into nothing. I regretfully realize that the full system, with its many years of difficult training, its rigorous and austere discipline, is not for me.
Again, it is necessary to find a master.”
Brama shrugs his shoulders. “Brother, people who are hungry look eagerly for food; those who are starving, however, will search like madmen. When you want a master as much as a starving man wants to eat, you will surely find one. Those who search sincerely will most assuredly be led towards him at the appointed hour.” “You believe that there is a destiny about the matter?” “You speak truly.” “I have seen some books——”
The Yogi (Brama)shakes his head. “Without a master, your books are mere pieces of paper. Our word for him, guru, means: ‘One who dispels darkness.’ The man whose efforts and destiny favour him sufficiently to find a real teacher, steps quickly into a state of light, for the master uses his own higher gifts to benefit the disciple.”
