While most of us have practices that lean toward one of the major faith systems, it seems to me that in the final measure, each of us has an entirely individual structure of beliefs that can resemble, but never be identical to, another person's.
I'm now 54, and for fully 30 years now, my spiritual practice has been most closely represented by Buddhism. I respond most positively to Buddhist philosophy because of its intellectual precision, its cool detachment, and its belief in following the evidence of logic and experience. In its better moments, Buddhism can be one of the most tolerant of belief systems, though it, too, can have its parochial moments, especially when it comes to individual schools within the Buddhist world passing judgement on one another.
Yet for all of that, when asked to name my religious membership, I take pause and have to acknowledge that I can't really say that I'm a Buddhist. I miss membership in the club because of a single belief that most definitely violates the rules for authentication as a Buddhist.
Strictly speaking, Buddhists simply do not believe in a deity called God, thinking that such beliefs are largely irrelevant to the the pursuit of enlightenment. That is, in fact, one of the central appeals of Buddhism, that it is free of the heavy-handedness found in most deity-based religions. The inherent atheism of Buddhism is the Achilles heel for me, the final membership requirement that just eludes me.
Because in my heart of hearts, an intuition tells me that underlying our experience is some kind of central Truth that universally present for all of us. This energy feels to me quite concrete,with an inherent intelligence and humor about it. It's not that I adhere to any kid of cult of personality when it comes to deity——I certainly don't think of God as some kind of uber-personality that dwells in someplace called heaven. But for all of that, the supernormal energy I sense is something that communicates with me when I choose to ask and listen, and it's distinct enough for me to feel a kind of "I-thou" relationship to it.
Uneasy about this lingering belief, I sometimes pretend that it's "buddha-nature" I'm sensing here. To no avail; something that feels a lot like God continues to lurk around the corner, like a drug dealer trying to tempt school children. At the end of the day, it appears I'm a Missouri-Synod Buddhist.
