This quote is from Charlotte Joko Beck. I never read any of her stuff but judging from this quote it looks like I would like to add here books to my reading list.
The quote is very Zen-like and when I looked up her work on eBay it just proved it.
Any bad moment that happens to us will be much easier if we see it as the right teacher that comes along.
When something like this comes up ask yourself the right questions. What am I supposed to learn from this? How is this beneficial to me? If you cannot think of an answer have faith and patience. It will reveal itself to you.
