(I've got the cabin fever today I think. This is as good a time and place as any to set this down...)
I believe that "we are not physical beings having spiritual experiences, we're spiritual beings having a physical experience", and so the lives we lead are not random, rather they are tailored (by angels?) to each soul to give it the experiences it needs to grow.
When Attenborough wonders at the cruelty of a God who would let e.g. a fly larva eat a child's eye, from my POV the real question (that I do not particularly want answered, because it scares me) is what mistakes did that soul make to get to the place where having such a terrible experience was the medicine it needs?
A devotee of Sai Baba wrote a book where she tells of seeing a woman holding her sick child and wondering why Baba didn't just miraculously heal the child, and later receiving a vision of the two souls in a previous lifetime where they had been a corrupt judge and his bailiff and together caused great suffering. To experience a life as a helpless mother and sick child was the medicine those souls needed to understand the consequences of their choices.
At this point I feel it's important to point out that reincarnation is common to all the major religions, including Christianity. Reincarnation was excised from Christian knowledge centuries after Christ, but they folks who did it didn't go so far as to edit it out of Jesus' own words, and He states clearly that Elijah and John the Baptist are the same soul.
Anyway, it seems clear to me that for many souls knowledge of Chi in their current lifetimes is not part of the educational curriculum.
However, I could be wrong about all that, and even if not there are presumably souls who are supposed to learn about Chi in this lifetime, so I bring it up from time to time.
