Https://www.heartscenter.org - David Christopher Lewis gives a teaching on song 9.009 Magda's Mantra from the prayer book of the Hearts Center community.
He says that this is an important prayer and visualization for the Hearts Center as it is a part of the mission of the Hearts Center as a community that is part of the Golden Crystal Age.
This concept of the crystal is very important as we are all really crystal-diamond beings of light, we are not just physical beings.
We focus on crystals because they are the enlightened aspect of minerals and this crystal aspect within us is the Christ consciousness which has mastered each one of the seven rays of light.
Through this we become crystal beings.
