A Zen monk has said, “When I eat, I eat; when I walk, I walk; when I sleep, I sleep.”
We live in a different way.
When we walk then we are talking in our heads.
When we are eating then we are planning ‘when am I going to study’.
And there is a great deal of parallel actions going on, obviously which is imaginary.
In reality, actions can never be parallel.
Existence does not allow multi-tasking. It says, “One thing at a time.”
