I hope everyone has a happy and healthy Thanksgiving.
Although most of us were taught otherwise, existence is interactive. We are not separate entities, each molecule separate, each person separate. Everything is interconnected in the very fabric of existence.
Our thoughts resonate through all of existence, and existence responds. This also is true about emotions. When emotions and thoughts are in agreement, knowingly or unknowingly, existence responds in a stronger manner.
So when you feel grateful for all that is given to us by existence, existence wants to give you more. If you are not grateful, and are resentful, then existence wants to give you more of that. Perhaps it is better to say that what you think and feel is reflected back to you in many ways.
So have a happy, healthy, and grateful Thanksgiving!
