This skull was found in Guatemala and was said to be used in many healing ceremonies in ancient Maya. The symbol below the skull is called an Antahkarana. The Antahkarana is a multi-dimensional symbol and is often called as a"RAINBOW Bridge" because this signifies the seven colours of rainbow as well as the seven chakras of the human body. From another perspective this symbol appears as a three dimensional cube. Its energy moves up from two to three dimensions that can be seen and continues up through unseen dimensions all the way to the highest dimension, the dimension of the Higher-Self.
The Antahkarana symbol is the one which is said to possess its own conciousness. The symbol is so powerful that it can work well and good independently of outside energy. It is a powerful symbol and simply by having it in your presence will create a positive effect on the chakras, aura and the surroundings.
It interacts directly with chakras as well as the aura and it knows very well as how much energy one needs. It cleanses and energises all the 7 meridians of the body running from top to bottom of human body. The energy emitted from these symbols moves upwards from spine of the root chakra to the crown chakra and again from crown to root chakra, downwards from front side of the body and thus the energy will be moving around and around throughout the body, thereby creating a perfect balance in energy flow and thus creating harmony.
