Happiness can teach us things, but yes happiness is more to truly take the time to be in the moment and appreciate what we do have. I have learned much from happiness simply because I am in the right state of mind for the thoughts, feelings and emotions that I need in order to manifest the life of my dreams. But darkness is what ultimately leads us down the path of personal transformation. And besides, I love a good challenge! :D
Unfortunately, many people, especially the older generation, have fears that are rooted back to when they were children. As we go through life we still have that inner child within us. The thing we must realize, however, is that we must use our inner child to create the world we wish to live in and use the adult version of ourselves to actually bring those things into the physical reality. Just like the Tao shows us, we live in a world of duality and our inner child and inner adult are also part of this dualistic world. So we must come together with ourselves and master both worlds!
:) Thanks for more elaboration of what i wanted to convey :)
