Think of the objects that you make use of (or even make) every day at work or school or in your own home.

Make an association between each one and some intention for prayer. You could do this on the basis of what the item looks like or is used for. For example, a pen could stand for communication between friends, relatives, or parties in dispute; a safe or locked cupboard could represent the inner mystery at the heart of all things; a corridor could represent the route to illumination. The more way-out the association is, the easier it will be to remember!
