The value of Self –Knowledge isn’t to be found in books. Those are just the external appearances of self; they're not the realization of “Self” as proof. If one realizes the “Self” he realizes the formless substance of the mind and he sees the truth in it. When the truth becomes apparent it cuts off the stream of delusion. Their writings are pointers to truth, not truth-in-itself. That's why merely believing in their books is pointless.
