Illness is something out of balance, rather than something within balance. It's been something that is created and it's been created for a purpose and a reason, and that purpose or reason may not be obvious to the person that has the disease. Nevertheless, there is something going on and it's not always easy to find that out.

It came to my mind that in the Yoga Sutras of Patanjali, in Indian spiritual literature, and in the Bhagavad Gita, and when I started reading about outstanding yogis and people of exceeding spiritual power such as Ramana Maharshi, or Yogananda, they all had the ability to do what we would call - I don't know what you would even call it - psychic phenomenon, magic, transform objects, be able to perceive the future, the past and the present simultaneously.

A lot of things occurred to me with shamans in Peru.There were a number of different kinds of experiences that you learn from doing ritual and taking ayahuasca [a common tropical forest hallucinogen] is the key to understanding the native consciousness and perception of the world with the Peruvian shamans that you wouldn't get unless you had been with them, but every shamanic tradition, including the Native American tradition of medicine and cleansing ritual, like the Sun Dance or the sweat lodge.

I describe the variety of different kinds of experiences I had, from seeing into the future to being inside the body of a bird and feeling the bird consciousness, to being in a plane of existence with beings that do not exist on this planet at all. And I described my experiences to shamans who started to laugh, saying, "Oh, we know those guys."

Dreams - Language in a dream is unspoken but understood. Words get in the way.

Most people who've never experienced non-ordinary states of consciousness and only hear them described tend to try to describe them in terms of the logical, rational way of looking at things, the so-called scientific explanation, which often leaves a lot lacking and doesn't really fulfill understanding the experience at all.

You had to be able to lift yourself outside of the time stream - and that essentially became what is called the yoga of time travel.
