We do not "come into" this world; we come out of it, as leaves from a tree. As the ocean "waves," the universe "peoples." Every individual is an expression of the whole realm of nature, a unique action of the total universe.
There are moments when troubles enter our lives and we can do nothing to avoid them. But they are there for a reason. Only when we have overcome them will we understand why they were there.
The instruction we find in books is like fire. We fetch it from our neighbours, kindle it at home, communicate it to others, and it becomes the property of all.
