In spiritual terms a gear signifies a change of consciousness. Moving up a gear suggests moving towards the spiritual and moving down, towards the physical or material. Psychologically we sometimes need to change perspective. This can be seen as changing gear in a vehicle, to alert us to changes that need to be made. In the vernacular, gear can represent both the paraphernalia associated with drug-taking and also clothes. We shall need to make some kind of link with the circumstances in our everyday lives. For instance, if in the drug-taking 'gear' a component is missing, we may be creating difficulties for ourselves. Insofar as clothes are concerned, we probably need to act more appropriately.
