A Sanskrit term (also spelled “Tattwas”) for symbols representing the elements. The Tattva symbols are very basic: Earth is a square, water a crescent, fire a triangle, air a circle, and ether (AKA spirit or Akasha) an oval. These five can be mixed. For example the fire triangle can appear inside the earth square, making “Fire of Earth.”

The energies represented by the symbols flow through the universe, alternating at different times. These are known as the “Tattvic Tides.” These can be used to determine the appropriate time to do a ritual.
