A man who was neglecting association with the "brethren" because he became involved with spiritism wrote a letter which was published in the May 1, 1912 issue of The Watch Tower ...
"I was very nearly trapped beyond hope of regaining freedom, in one
of Satan's most successful devices, viz., Spiritism. I was induced
to purchase a "ouija" board, "just for amusement"; but
I dare say that that "amusement" almost cost me my "crown."
I spent all my spare time in operating the "board," and
became so skilled in its manipulation that it would perform
rather difficult feats with the least solicitation. ... I can easily see that Satan, the chief operator of all "ouija" and planchette boards, was only trying with all his might to get me more firmly into his clutches. My good morals were
not entirely destroyed, however, and the adversary, knowing
this, advised me not to neglect my brethren or my Bible. I
then asked whether the Dawns are a correct interpretation
of God's Word. To this the reply came, "Yes; the Dawns are
correct, not only in doctrine, but in chronology as well." I
then asked by what power the board was operated. It answered,
"By evil, spirit power." It further confessed to me
that the spirits who operate the board have no other mission
than to hinder all of the Lord's people. It further stated that
tbey took "special delight in buffeting, hindering and endeavoring
to ensnare Brother Russell and his co-laborers at the Bethel Home".

... There you have it. Satan confirmed that Studies in the Scriptures were accurate in doctrine, chronology, and encouraged this person to associate with the brethren and read the Bible.
