If your mind is fixed on a certain spot,
It will be seized by that spot and
No activities can be performed efficiently.
Not to fix your mind anywhere is essential.
Not fixed anywhere,
The mind is everywhere
The Original Mind is like water which flows freely
Whereas the deluded mind is like ice
There is a passage in the Diamond Sutra that says:
"The mind should operate without abiding anywhere."
- Takuan (1573-1645)
