You could work with the five buddha family principles by picking up a piece of stone or a twig and approaching it from each of its five different aspects. With each family, a whole different perspective will begin to develop. At that point, you have limitless resources. You don’t feel obliged to produce ever more materials, because you can take one thing and make it vajra, karma, padma, ratna, or buddha. You can make all kinds of tartan plaids out of that.
