In The Beginning: H.P. Blavatsky
Helena Petrovna Blavatsky:
Perhaps all of her work can be summed up in one of her maxims: Compassion is the law of laws. She explained that brotherhood is not a mere ideal – it is a fact in nature on the spiritual plane. From that we derive a logical basis and a binding source for morality that can guide and inspire us, even while more traditional religious sources are losing their compelling force. She gives us the metaphysics from which we can deduce the most important principles of how to live.
Theosophy offers the ultimate spiritual challenge
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 reward past all telling – the power to bless and save humanity; for those who fail, there are other lives in which success may come.
