An in-depth study of Western and Eastern religions shows that, each in its own way, they lead the spirit to reflect on essential questions. If we look at several of them and get to know their very high spokespeople, the hardest thing is to decide on one or the other, rather than both and all of them. Beyond convenience, however, it seems necessary to choose so that the practice is guided and reinforced by a tradition. It may be an arbitrary choice, but it results in a compromise that is almost always enriching.
