Honoring one’s patron deity (or any guardian spirit) as a daily routine will ensure a steady connection. Such spirits are around all the time, but maintaining a close bond offers peace of mind, as well as a more conscious awareness of that spiritual presence.
I light a candle every day for my patron deity, the Norse God Loki. He has been with me in various forms throughout my life, and though I know he is a constant presence, performing a daily ritual allows me to focus on him regularly.
Prayer and various rituals for certain occasions are always significant, but a simple daily ritual will ensure blessings from a patron/guardian on a regular basis. I light a candle each day as part of my daily routine, just as I have a bath, brush my teeth, and prepare meals. It becomes second nature, and magic is routinely practiced.
In some of my contact with other Pagans, they often wonder how to summon a patron deity. It is actually simpler than one might imagine; spiritual entities may exist beyond the physical plane, but they can always be accessed. Formal ritual and spell work are useful, but not necessary. Treat a patron as a close friend. A simple ritual of acknowledgement will keep the connection strong, and guarantee a greater channel of communication.
I light a candle daily, but any simple daily activity of one’s choosing will be just as helpful. There is never physical distance between a patron and his/her charge; simply reach out, and the bond will strengthen.
