“From the preceding extracts and those of the first chapter of the present work, the intelligent reader will readily perceive the strong affinity which exists between the principles of the Vedas of India and the metaphysical and philosophical writings of the (Pythagorean) Sufis. The religion of Brahma has been carried into Persia and even Arabia, and been engrafted upon that of Islam by the dervishes.”
