H. P. Blavatsky
If the “false prophets of Theosophy” are to be left untouched, the true prophets will be very soon—as they have already been—confused with the false. It is high time to winnow our corn and cast away the chaff. The T.S. is becoming enormous in its numbers, and if the false prophets, the pretenders . . . , or even the weak-minded dupes, are left alone, then the Society threatens to become very soon a fanatical body split into three hundred sects—like Protestantism—each hating the other, and all bent on destroying the truth by monstrous exaggerations and idiotic schemes and shams.

(Lucifer, March 1889; Collected Writings 11:47-8)
