This classic commentary on H P Blavatsky's Secret Doctrine is now back in print in its original edition, with two appendices and in a new expanded index. De Purucker's comprehensive overview of this 'conscious, spiritually purposive universe', includes the seven jewels of wisdom: including karma, reincarnation, self-becoming, hierarchies, psychology and pneumatology of the universe, space, the boundless all, the microcosm, mirror of the macrocosm, interpenetrating spheres of being, the nature of matters and consciousness.
