How can one become enlightened in one single moment? One can, because one is enlightened -- one just has to recognize the fact. It is not something that happens from the outside, it is something that arises from the inside. It has always been there but you were clouded, you were full of thoughts.
One minute was enough, Tyler said, a person had to work hard for it, but a minute of perfection was worth the effort. A moment was the most you could ever expect from perfection.
The pain that you create now is always some form of nonacceptance, some form of unconscious resistance to what is. On the level of thought, the resistance is some form of judgment. On the emotional level, it is some form of negativity. The intensity of the pain depends on the degree of resistance to the present moment, and this in turn depends on how strongly you are identified with your mind.

The psychological condition of fear is divorced from any concrete and true immediate danger. It comes in many forms: unease, worry, anxiety, nervousness, tension, dread, phobia, and so on. This kind of psychological fear is always of something that might happen, not of something that is happening now.
