How did the Universe begin?
I'm not sure this is something we can answer. . . but I do imagine that whatever the answer is, it would amount to a great knitting together of all the fables and scientific versions we have so far. There is something in us, deep in our souls, that might know or remember in some way and I think that creeps out into our stories.
What is the origin of good?
Acknowledging the other. . . when you start to understand that there is what what you are/know/do and then there is the other (what you aren't/don't do/don't know), you can begin to see the size of your self in a more realistic way. This is the beginning of understanding what would happen if every single person did the same thing you are doing RIGHT NOW. Think about being the point of origin of a behavior, as if all those people did something because you did it. I, personally, want what I put out there to result in more positive than negative. And in more "greater good" where we all benefit, together.
What is the origin of evil?
Selfishness and self-absorption. . . when we think of our selves as the only thing, we cannot act in a way that doesn't harm others.
Is there free will?
Yes, there is free will. Our ability to access it depends largely on our ability to elevate our awareness to see and understand what influences our thinking.
How do you find happiness?
I'm working on this. I'll let you know. The only thing I am certain of right now is that happiness is not found in manufactured food and chemicals parading around as food.
How do you find truth?
Trust is the amalgamation of aspects and experiences. If you think there is only one viewpoint or way to see a thing, you have not found the truth. You have to be able to see the same thing from multiple points-of-view and construct the whole thing in your mind. This gives you a better understanding of the context of the thing. . . which is an integral part of the truth of it. . . because it defines what influences who sees it and how. Which will always be a part of constructing an un-truth and so it MUST be a part of what IS truth.
