AC or DC mind?

The difference between Direct Current and Alternating Knowing (DC or AC) is a matter of time. In direct knowing, there is no gap between the knowing and the known.
In AC there is a choice or gap: should I choose the high or the low of the wave? Oh...they are moving, so when I choose the high, I also choose the low...Catch 22.
Zen is DC, the world is AC.
