This energy is amazing to watch. This is called murmuration.
How do they do this?
There is no leader, no fish says, "Hey, follow me!"
They pick up on the energy - call it muscular telepathy.
One flinches in muscular tension and output and the others sense the commotion in motion and follow immediately.
These fish sense the energy of the other fish and they create ONENESS in their motion by moving in the exact same direction at the exact same time to the same degree.
They can remain in this energetic force for long distances too!
How divine, they are creating a powerful upward spiral of combined energy in action.
