Spiritual sciences are an important part of human education. We think we are worldly beings who want a spiritual experience . THE REALITY IS THAT WE ARE SPIRITUAL BEINGS WHO HAVE REINCARNATED FOR A WORLDLY EXPERIENCE. Therefor even for worldly activities , the root of the drive that empowers us lies in our eternal spiritual origin. Like children can never be separated from parents because the parents live on in the DNA of the person and his progeny. Similarily even the greatest atheist or adamant scientific mind carries the cosmic power within , only choosing to work on one side of the potential within and ignoring the spiritual base which is the never ending source of human potential .
Tarot is a shruti , developed as a spiritual concept to help people to peep into the nature within them and outside them . It is a torch-bearer that uses divine light to show us the path in the darkness of ignorance.
