We are spirits inhabiting a body or incarnated, it is obvious that our reality involves both material and spiritual aspects. However, until now formal science has focused all its efforts to answer the questions about the physical part of our reality.
This means that we have been trying to understand the reality around us with only half of the necessary information; the other half of that information comes from the knowledge of the spiritual dimension for which it is necessary to have a spiritual science.
That is the vacuum we seek to fill with the Spiritual Theory, the theoretical foundation of the Spiritual Science.
