"How far she was ever the deceiver depicted by Mr. Sinnett in his posthumous publication "The Early Days of Theosophy in Europe," may be judged by the reader if he will study the letter from Master K.H. in which he gives his own opinion on her delinquencies. Those who love the memory of H. P. Blavatsky for her work and the gifts she gave them, cannot but feel after reading that letter that after all she was worthy of their high regard; and those who have tried to blacken that memory and minimise the value of the work she did, will rise to heights indeed if the prayer be granted — that they may never deserve worse condemnation."
