In geometry, a torus (plural tori) is a surface of revolution generated by revolving a circle in three-dimensional space about an axis coplanar with the circle. Real-world examples of toroidal objects include inner tubes.
The Torus is the aura at the sacred geometrical level which gives & receives energy. The Aura is the connection points of all your chakras together which creates the vortex energy, the balance of yin & yang.
Sacred Geometry grids are designed to work with sets of crystal healing stones to assist in manifestation for a specific intention or purpose. Sets of crystals & stones are used for ritual magickal or spiritual crystal healing purposes or with Reiki-Seichim energy work for healing.
Reiki programmed and energised crystals are also available for crystal grid sets to work with a specific intention.
