The traditional way is not unique. There are many traditions which are useful in the soul’s issue. This is, by the way, the reason of the existence of syncretism.  A tradition is considered unique only in a dogmatic way. But the dogma has no relation with Faith. The traditional way is the use of the network of Humanity to study the access to the souls. It’s not just a communication or even an understanding. It’s more deep and more complex. That’s why we talk about an alloy which is related with the notion of essence. It’s a kind of blend of essences, which can be sacred in several cases at least in tradition.
