Aha! EBay has another envelope addressed to A. Victor Segno of the Segno Success Club, 701 N. Belmont.
Segno, author of such books as "The Law of Mentalism," "How to Be Happy Though Married" and "How to Have Beautiful Hair," was a mentalist with a simple scam: For a $1 a month, he would send out a mental "success wave" twice a day. And it was quite successful–for him. In a few years, he was able to build an elaborate center in Echo Park (now demolished, apparently).
The Power of Thought
by A. Victor Segno
"I hold it true that thoughts are things
Endowed with bodies, breath and wings,
And that we send them forth to fill
The world with good results–or ill.
That which we call our secret thought,
Speeds to the earth’s remotest spot,
And leaves its blessings or its woes,
Like tracks behind it as it goes."
"We awaken in another
Just the thoughts our minds contain.
If we’re kind, we win their kindness,
If we hate, they hate again.
We pass on to brother mortals
The vibrations of the soul,
And the knowing ones receive them,
As they search from pole to pole."
"We build our futures thought by thought,
Or good or bad, and know it not–
Yet so the universe is wrought.
Thought is another name for Fate,
Choose, then, thy destiny and wait–
For love brings love and hate brings hate."
–The Law of Mentalism, A. Victor Segno, Los Angeles, Calif., 1902
