Thats so wonderful. Eckhart talks about that in the chapter "Beyond happiness and un-happiness there is peace". He states:
""""There have been many people for whom limitation, failure, loss, illness, or pain in whatever form turned out to be their greatest teacher. It taught them to let go of false self-images and superficial ego-dictated goals and desires. It gave them depth, humility, and compassion. It made them more real.
Whenever anything negative happens to you, there is a deep lesson concealed within it, although you may not see it at the time. Even a brief illness or an accident can show you what is real and unreal in your life, what ultimately matters and what doesn't.
Seen from a higher perspective, conditions are always positive. To be more precise: they are neither positive nor negative. They are as they are. """""
For me, the realization came back in August of 2006 and that "I can't go on like this" thought, led me to a group therapy and then to a shrink who then led me to AA. Around 2009 a friend of mine got hooked me to ETs work. Incredible piece of work. It takes you beyond your mind.
Like you said, we just have to remember to go back these teachings. Thats the key.
