"Everything is already available; we have to develop the capacity to receive it."---Annie Besant In her metaphysical work, pioneering Theosophist Annie Besant (1847-1933) drew from the ancient wisdom of the East to explore the deep recesses of the mind. The original edition was published in 1903 and has been in print ever since. Now leading contemporary Theosophists have painstakingly revised the text to free its timeless truths from the time-bound language of the early twentieth century and make it more accessible to today's readers. The result is a clear discussion of subjects of increasingly high interest: concentration, memory, consciousness, telepathy, sleep and dreams, cultivation of the will, and access to your higher self.
