Except living organisms, nature has no means for expression of consciousness on a level of complex thought and it has no means to experience changes within itself without physical senses to do so. Without complex thoughts and some detection mechanisms there cannot be any meaning to any action. This means that the nature is intrinsically non-dualist.
There is an undeniable connection between humanity and Earth in the world. Serenity in the environment is as crucial as serenity within ourselves for life full of peace, prosperity and personal development on every level humanly possible.
