But on to the OP -- they all make sense, each in their own unique way.
And they have quite a few things in common as well.
I've found useful things in each of these religions, and put them into practice as much as I can in life.
From Hinduism, I take the cyclical view of history, the idea that people have different approaches to life and to God and that this is not just "ok" but downright necessary for life to work.
From Buddhism, I take the Four Noble Truths, most especially the one that instructs us that attachment is the source of suffering. Whenever I am upset or angry, that's a sure sign there's an ego attachment somewhere. The solution to the anger is not to vent it, but to remove the ego. Where there is no attachment, there is no anger.
(If I had to phrase this in a Christian context, I'd say that "acting out of our own will instead of God's will results in sin, and that creates suffering")
From Taoism, I take the idea symbolized by the Tao itself. Creation is an ever moving mix of opposites. The way is to put these opposites into balance as much as we can. Also, "around is better than through"
Taoism and Buddhism have helped me mellow considerably in life.
I couldn't find that in the Christianity I was raised with, though it's there also. It's just that, raised in an environment where so much emphasis was put on "sin" and "hellfire" especially the part where we were pointing fingers elsewhere instead of looking how to improve ourselves, it was too negative and so not constructive. Had I run across the Christian mystics earlier, I may have had different results. But my denomination was not exactly what you'd call mystical.
