When we are clear enough about our own point of view, we can find help in the methods of Eastern Christianity or in the ways of the Far East, perhaps by consulting the I Ching or through mandala contemplation; we may even find help in the ways of shamanism or Islam. If we are clear about where we stand and the direction we must take, such methods may be useful in order to follow our own way to the end.
