The repeating chemical structure of crystals is said to invest them with a kind of memory. This means that crystals have the power to hold energies. You may hold a quartz crystal with the intention of filling it with your love. This is what is meant by programming a crystal. You do not need any wires or a special connection with God - all you need is intention and focus. The crystal will remember your love, which will then permeate any environment in which the crystal is placed. Crystals can remember negative as well as positive energies and so will sometimes need to be cleansed. For instance, an amethyst will actually help to cleanse a room of negative energies (eg. anger) but this means that the amethyst, which will retain an element of that negative energy, will itself occasionally require cleansing.
There are various ways of cleansing crystals. One of the most common is to submerge them in salt water (sea water is excellent) for a couple of days, then run them under the tap to clean off the salt. Other methods include burying crystals in the garden for a few days, leaving them for a while in a stream (pick a slow-running one, or they may no longer be there when you come back for them!) or leaving them outside overnight in normal water to bask in the moonlight.
