Everyone has 3 dimensions. The physical, the personality which we express and the inner, which is constant and isn't always visible to the world. Every aspect of existence has 3 dimensions. Past, present, and future. Creation, maintenance, and dissolution etc. Each of the 3 is available for exploration, but the best one to concentrate on is the current dimension, the present. That is how we nurture purpose, focus, and clarity, which create a great life and a great future.
