“During this state, do not become dull, absent-minded or apathetic.
Is it not true that you cannot verbally formulate that the identity of this mind is such-and-such, nor can you mentally form a thought of it? Rather, isn’t it a totally unidentifiable, aware, unconfined and lucid wakefulness that knows itself by itself? Within the state of evenness, look to see whether it isn’t an experience without any ‘thing’ experienced.”
The master then lets the disciple look.
“That’s called vipashyana.”
