In other words, it is fit for work, ready to know. This is the degree
of concentration to be aimed for, not the very deep concentration
where one sits rigidly like a stone image, quite devoid of awareness.
Sitting in deep concentration like that, one is in no position to
investigate anything. A deeply concentrated mind cannot practice
introspection at all. It is in a state of unawareness and is of no
use for insight. DEEP CONCENTRATION IS A MAJOR OBSTACLE TO INSIGHT
PRACTICE. To practice introspection one must first return to the
shallower levels of concentration; then one can make use of the
power the mind has acquired. Highly developed concentration is just a tool.
