This particular type of Rosary of the Seven Rays is used in devotions to the Seven Joys of the Blessed Virgin Mary. This devotional practice is a prayer and meditation method that can raise human consciousness, and this particular rosary is designed according to techniques that focus on the heart chakra. Thus it is an excellent tool for those working with esoteric prayer and those who need help in opening and balancing the heart chakra. It can also be prayed on behalf of those who need divine assistance with emotional and spiritual imbalances and is a powerful tool in the arsenal of healers and lightworkers.
Entire piece is 22.5 inches long from end to end. Decade loop is 18".
This is a serious piece for the serious practitioner devoted to esoteric prayer. It won't do you much good if you just keep it in its bag and look at it a couple of times a year - it's not like a talisman you keep in your pocket. It's more like a musical instrument -- it's designed to be used, and its powers increase with regular use.
Bishop Tau Michael Bertiaux says of the rosary, in his chapter on Upadhi I in The Voudon Gnostic Workbook, that prayer beads are among the most effective ways to generate spiritual energy and "hook up" to God energy. He conceives of the rosary as a "prayer machine" and emphasizes that the rosary is further blessed and empowered through use. I have blessed and empowered this rosary, but it will absorb deeper spiritual energies through your repeated use. For more information, see The Voudon Gnostic Workbook.
