Practical Occultism
H.P. Blavatsky
Col. Wr. XIII, p. 219

There is a road, steep and thorny, beset with perils of every kind, but yet a road, and it leads to the
very heart of the Universe:

I can tell you how to find those who will show you the secret gateway that opens inward only, and
closes fast behind the neophyte for evermore.

There is no danger that dauntless courage cannot conquer;
there is no trial that spotless purity cannot pass through;
there is no difficulty that strong intellect cannot surmount.
For those who win onwards there is a reward past all telling
- the power to bless and save humanity;
for those who fail, there are other lives in which success may come.
