The dû was first dreamt up by Phil Parker whilst he was working with clients who had tried everything to get improvements in their lives and health and yet consistently remained stuck.
People found that just by starting to use the dû they could change their whole view of the world and themselves, and change and opportunity naturally followed. Areas of their lives or dreams which had appeared to be impossible to navigate, became reachable, relationships improved and laughter and happiness replaced flatness, despair and hopelessness.
This was a good thing, and use of word dû spread, first to Norway and Scandinavia, then Australia and New Zealand, USA, Canada, Cuba, Europe, Asia. Russia and Africa.
