When you walk or drive down a city street, what you are seeing all around you are manifestations of thoughts.
Every building began as an idea in somebody’s mind. Somebody acquired the land. Somebody designed the house. Somebody had the idea to organize people together to build the house, either to make money or to live in it. The trees you see were planted for shade in the yard, on the sidewalk, along the street. The pavement that we accept as a “natural” part of our landscape was conceptualized, designed, engineered, installed, and is maintained via thought.
Thoughts create our physical reality, and they also create our larger reality. During ancient times, when there was an electrical storm, people perceived the thunder and lightning as the voice of a powerful deity. If somebody got hit by lightning, that proved to others that the person had committed some crime or displeased the deity.
When the thunder rumbled loudly nearby, people knelt to the ground and cried out their prayers. They knew, when they saw the awesome streaks of light across the sky, that they were seeing the finger of their god writing messages or expressing an opinion.
