Following up on "luck"...
I am sure you know people who are always unlucky. Or seem to be.
I had a colleague once who had a reputation for always winning. And sure enough, she did. At one company party there were four prizes to be won by lottery amongst 400 employees. She won two of them!
I think being unlucky is the condition of your higher mind telling you something.
And being lucky is being in alignment with your higher mind.
I think we each have a human body/mind/beingness which is a tiny tiny part of a huge Higher Mind which goes beyond time and space.
Beyond that is a higher mind for all living things.
And beyond that is God or infinity.
And I think our goal in life is to harmonize all those.
The main barrier to this is that our Human Mind is jealous and proud, and hates to share control and credit with the higher minds. We need to learn to let go of that.
