This simple and quick technique is based on the work of David Grove. This process, known as 'Emergent Knowledge' is even 'cleaner than clean', in that the process relies mainly on repetition of the same kind of question 6 times which has the effect of adding a deeper understanding of the same kind of knowledge, until everything the client understands reaches a kind of critical mass – and a new level of understanding breaks through.

As a tool for coaching, the client's metaphors give you an insight into their unique perception of their situation and their goals. When the client tells you that they can 'see light at the end of the tunnel', that is what they are experiencing. There is light for them, and they are in a tunnel. They will unconsciously 'know' much more about their situation from this metaphoric viewpoint.
