Esoteric Buddhism

The ultimate destinies of our race — concerning also the nature of other worlds and states of existence differing from those of our present life — checked and examined at every pointy verified in all directions and constantly under examination throughout has come to be looked on by its custodians as constituting the absolute truth concerning spiritual things, the actual state of the facts regarding vast regions of vital activity lying beyond this earthly existence.

European philosophy, whether concerned with religion or pure metaphysics, has so long been used to a sense of insecurity in speculations outrunning the limits of physical experiment, that absolute truth about spiritual things is hardly recognized any longer by prudent thinkers as a reasonable object of pursuit; but different habits of thought have been acquired in Asia.

The secret doctrine which, to a considerable extent, I am now enabled to expound, is regarded not only by all its adherents but by vast numbers who have never expected to know more of it than that such a doctrine exists, as a mine of entirely trustworthy knowledge from which all religions and philosophies have derived whatever they possess.
