When the water fills the first (outside) coil of hose it starts spilling over into the bottom of the second coil and forms an air trap which will prevent more water from entering the first coil.
This ‘trapping’ seems to be similar to what happens with all the past thoughts and beliefs we have had. They flow deeper and deeper into our mind and become trapped like the levels of water.
They’re harder to find, and the quality of their essence becomes more difficult to remember.
But, for some also obscure reason, we permit them to continue to rule our lives without even an interruption.
