It
is a good practice to constantly maintain all your divinity tools at its
optimum energy level. Divinity tool refers to crystals, oracle cards, prayer
instruments, music instruments, essential oil, scrying objects, and etc.
For
instance, you may place a clear quartz pyramid on your oracle cards to ensure
the energy level is cleansed and purified at all times. Grid crystals around
your mandala to amplify its energy level, maintain a constant energy download,
or whichever intention you intuitively decide.
There
are no hard and fast rules on the type of crystals to use, the shape or
intention to where it is placed. Be creative, and decide intuitively.
