According to "The Laws of the Sun", the truth about the soul is that we are a part of Buddha and are playing a part of His self-expression.
Also, it is written that "Past religions and sophisticated philosophies have developed and passed down in order to awaken people on earth to this truth. The ultimate purpose of natural science and space science, which are now making tremendous progress, is to reveal this truth about the soul."
Hystorically, great philosophers were often great mathematiciens like Pythagoras and Descartes.
Plato put mathematics as the gate of philosophy.
Kitaro Nishida considered religion as the untimate end of philosophy.
Traditionally, since Pytagoras and Plato untill Decartes' unification of geometry and algebra by the oordinate system, astronomy had been considered as a part of mathematics.
Furthremore, since Newton, mathematics is the foundation of natural science and space science.
Therefore, we, the Institute of El Cantare Mathematics, think that the ultimate purpose of mathematics is to reveal the truth about the soul.
