“Enq: Then, what I have heard, namely, that many of your Theosophical writers claim to have been inspired by these Masters, or to have seen and conversed with them, is not true?
Theo: It may or may not be true. How can I tell? The burden of proof rests with them. Some of them, a few – very few, indeed – have distinctly either lied or were hallucinated when boasting of such inspiration by great Adepts.
The tree is known by its fruits; and as all Theosophists have to be judged by their deeds and not by what they write or say, so all Theosophical books must be accepted on their merits, and not according to any claim to authority which they may put forward.”
