Contemplation: "Unfindability"

After reviewing the guidelines for practice, take the following as your contemplation:

If one observes the mind and searches for where a thought arises, where it remains, and where it goes, no matter how much one researches and investigates this, one will find nothing.  It is this very 'unfindability' of the arising, the abiding, and the passing away of all thoughts which is the greatest of all finds.
