You actually know all you need to know. If you can locate a post, maybe within the past two weeks, which asked if anyone had had a near death experience, I replied with the start of my own experience. The whole thing is too long and bizarre, but I know what I learned, I know it was real, and I know to recognize when someone is on the right track. You are.
Religion really doesn't matter and can sometimes be obstructive. Jesus' parables taught reincarnation and karma, but try telling that to a Christian. The heart of Christianity is perfecting the soul so it qualifies for advancement up the god system (which is also tackled in the parables), not having faith which qualifies your soul to be saved by another. It's up to the individual soul to progress and a huge part of that development is helping others, which Jesus overtly insisted upon, but which many ignore.
You mentioned that food, etc. wasn't important. Well, keeping yourself healthy is, but I know what you mean. Add to your list of what is unimportant to the soul: human physical features, focusing on genitals. The soul itself is pure energy. It doesn't have eyes, legs, or sex organs. There is no soul judgment as to where or with whom one has sexual relations. Love is love, lust is lust. Heterosexuals lusting after one another is just as earthly as homosexuals lusting for one another. Heterosexual lust isn't divinely sanctioned. The Source energy has never seen or experienced a penis in all its existence, so how could it be important to it? One's sexual behavior is earthly; soul couldn't care less.
Tamum!
