passage from article: A student asked Dezhung Rinpoche about visualization practice and deity meditation. Dezhung Rinpoche closed his eyes, scrunched his forehead, bobbed his head up and down as if he were concentrating very hard and said, “You visualize the head of the deity, then you visualize all those arms, then you visualize the implements, then the palace, then you try to see the whole deity clearly, but you lose one part, so you go back to visualize that… And it’s all gone. You start again, and the same thing happens, again, and again.” Then he opened his eyes wide, looked right at the student, smiled, and said, “And then you have a headache!”
