This is yet another of the fortune teller works I am so fond of. This one is quite short but dense and contains several novel inclusions- it is, as far as I know, the only work which prognosticates by nail shape and color (at least among works I've edited currently) and the tree picture is itself a sort of oracle used with a blindfold to tell general fortune.
This is one of a series of four booklets written in the early 20th century by Besant to show the basic premises of Theosophy to newcomers. It was out of a realization, on her part, it seems, that much Theosophical literature was too long and/or obtuse to be understood unless a person was relatively highly literate or already trained in Theosophy.
