On perennialism "There are as many paths to God as there are souls on the Earth." (perennialism)
Although it is a bit magniloquent sentence, i can say that it epitomizes a perennial position.
On the other hand, the paths in question are different (or cognate) traditions whom people can follow, then i can say that without traditionalism, perennialism turns into a kind of unamenable syncreticism. All new age bullshists comprises of this type of unamenable manners. We can compare traditions with different kind of architectural systems. All of them are tested, practiced and developed throughout ages, they contained experiences of ages and if you decide to construct any kind of building you would practice one of them. If you are a master, you can devise new one, possible.
However, there is no doubt that all masters are not real masters, some of them are false and this is another subject. Without a reliable path(tradition), you can not reach the goal. Because of this reason, most of well-known perennialist ( such as Sayyed Hussein Nasr or Rene Guenon) are also traditionalists.
