This practice to deepen our understanding of the spirit world is to use the 3rd eye to view the 5th dimension. The 5thdimension is our body's "perception" of the outside world, that is, the direct seeing, hearing, smelling, tasting, or skin feeling of the material world from the senses, even to the very subtle cellular level. The 3rd eye is the union of our soul and spirit. When we look at the 5th dimension with our 3rd eye, our perception of the world is not limited to the material world, but is combined with both the soul and the spirit, so we can perceive the world of the soul and the spirit, which is the complete world.
