The Eighth Chakra, (not visible on the most of the existing photos of paintings about chakras) is the seat of the soul: The conflicts of a human’s life are directly proportional to the distance at which energy of personality exists separately from the harmonic frequencies that emanates from the divine spark or soul. The Seat of the soul, the eighth chakra holds the ancient knowledge of our soul contracts and ultimately, our life purpose.
The 8th Chakra is the energy center of divine love, of spiritual compassion and spiritual selflessness. The seat of the soul is the major core star of our energetic system, also holding the records of on what our souls had agreed as specific lessons in our upcoming lifetimes and past lives.
