B1237 <=> B1239 [BTG XLVIII From the Author, p. 1238]

After the books of the first series have all been published, I intend for the spreading of the contents of the second series, to organize in various large centers simultaneous public readings accessible to all.

And as regards the real, indubitably comprehensible, genuine objective truths which will be brought to light by me in the third series, I intend to make them accessible exclusively only to those from among the hearers of the second series of my writings who will be selected from specially prepared people according to my considered instructions.
