The world needs more time in nature if you ask me. I go there to think and clear my head. I work things out and release the negativity that has built up. I read once that nature, being an infinite source of positive energy, can absorb your negative energy and it’s gone. One exercise is to throw rocks into a creek or pond or whatever source of water you can find. Name your worry or thing you need to let go of and fill that rock with the pain, the disappointment, the problem whatever you can name and throw it. It’s this act of releasing the negative that will free your mind and let the natural world comfort you.
It’s a simple solution really and it’s free.
