All the different religious traditions can be traced back to an experience of communion with the Ultimate by their founders or reformers. Historic circumstances lead then to the great diversity of religious traditions. Yet all those diversities are only so many expressions of one and the same mystical core — expressions of the sense of ultimate belonging. This mystical core needs to bring forth so many different myths and teachings, needs to be celebrated in so many different rituals, because it is inexhaustible.
