Listening for the End of Thought

Ajahn Viradhammo notes that if we are preoccupied with the conditioned, we cannot be available to the unconditioned.  To learn about dullness or anxiety for example, we make an effort to sustain our awareness on the changing nature of conditioned phenomenon. He also speaks on being patiently aware of negative judgments as objects of mind as well as noticing the habit of creating self-perception.
