Seated in a local Berkeley coffee shop many years ago I experienced a period of hyper- alertness that I am happy to now put a name to:  deep travel.  Every sound, shape, movement and smell seemed to take on an intensity I had never imagined existed.  It is quite a relief to know I was not in a semi-psychotic state that morning but rather that this sparkling moment of clarity  is anexperience I share with other deep travelers.
