I've written about this below - emotional evolution and healing - many times and in different ways. It's such an important part of our growth on this planet, individually and collectively, that it's worth going over many times. At least I think so. Change is a process and the spark and insight has to come from within. 

This here is what I constantly cultivate: 

Inner peace is not the same as never being emotional. In fact, it's the complete opposite. Our emotions are only states of being which we move through. What we feel at certain times, for whatever reason, is our human experience. The mistake we often do is that we either suppress our emotions or we gossip about them, or we lash out. If we are still enough and open when an emotion arise, if we fully feel what is going on inside, then it will pass. It's only an experience, not who we are. The energy will simply peak and leave. It's like being in a spinning wheel where the core is moving peacefully, but further out the speed and energy can be quite frantic. We can sit in the middle and experience all of the wheel without getting caught in the storm. We can peacefully flow through life, while feeling all of it all the same. Or, we can let ourselves be thrown into the spin. I wish to find my center in this way since I feel it's not only part of my own evolution, but of the entire world. Our way to peace goes via the within.
