What is the greatest mystery of the universe?

The Ancient Mysteries

Of us is perfectly true what is said in the Bible―

Many prophets and kings have desired to see those things, which ye see, and have not seen them, and to hear those things, which ye hear, and have not heard them." ―(Luke, x. 24) 

Because this honour is reserved for us, and this opportunity is given us, it seems to me that a great responsibility rests upon us and that we should try to be worthy of the gift. It is good Karma, which allows this possibility to open before us. If we let it pass, we shall not deserve to have another offered us for thousands of years. If you knew, as I know, with what difficulties we had to contend in former days to learn all those things, which are laid before us now, perhaps you would appreciate more the opportunity offered you. 

Let us try to make use of it to the utmost of our power and show ourselves worthy of the privilege given us by Theosophy.
