There is a group of crystals that seem to lack frequency and power but actually do the opposite.
They are called zero-point crystals. They calm the energy and put you at rest. These are very special and rare crystals that shut down everything, like being inside a black hole where nothing can escape, or being in infinite emptiness where there are no more boundaries. This shutting down is the same as stretching the limits to infinite. Infinity and zero are one and the same with these crystals; infinite frequency is like zero frequency. These crystals do not feel strong; however, do not underestimate them as they will put you into stillness and quiescence (silence).
