"When we talk about the tantric world, we are talking about this visual, auditory, sensory world, which has not been explored or looked at properly. Nobody has bothered to actually experience it. People just take it for granted. We may have been interested in our world when we were little children, but then we were taught how to handle it by our parents. Our parents already had developed a system to deal with the world and to shield themselves from it at the same time. As we accepted that system, we lost contact with the world. We lost the freshness and curiosity of our infancy a long time ago. And now, although the world is full of all kinds of things, we find that in communicating with the world we are somewhat numb. There is numbness in our sight, numbness in our hearing, numbness in all our senses. It is as though we had been drugged. The reality of the world- the brilliance of red, the brightness of turquoise, the majesty of yellow, and the fantastic quality of green- has not been seen properly. We have been indoctrinated, or we have indoctrinated ourselves. The point of tantra is to reintroduce the world to us. A direct relationship between teacher and student is essential in Vajrayana Buddhism. People cannot even begin to practice tantra without making some connection with their teacher, their vajra, indestructible, master."
