"…As the dawn of physical science broke into glaring daylight, the spiritual sciences merged deeper and deeper into night, and in their turn they were denied. So, now, these greatest masters in psychology are looked upon as “ignorant and superstitious ancestors”; as mountebanks and jugglers, because, forsooth, the sun of modern learning shines today so bright, it has become an axiom that the philosophers and men of science of the olden time knew nothing, and lived in a night of superstition. But their traducers forget that the sun of today will seem dark by comparison with the luminary of tomorrow, whether justly or not; and as the men of our century think their ancestors ignorant, so will perhaps their descendants count them for know-nothings." ―H. P. Blavatsky, Isis Unveiled: Chapter II, “Lost Arts”

Modern science, focused upon the investigation of material phenomena, lacks effective methods for knowing the hidden, spiritual roots of existing things, precisely due to the fact that such mystical principles can only be apprehended by conscious perception beyond the limits of physical matter.  Whereas the methods of empirical investigation end at the limits of materiality, Gnostic science begins where physical science leaves off: through the awakening and development of consciousness.  It is by cultivating the ardent faculties of the soul that one can obtain the mystical apprehension of fundamental truths.  The direct cognizance of the intelligent blueprints of nature is therefore born from the scientific procedures beyond the reach of the five physical senses.

Learn how the ancient schools of mysteries, whether from Rome, Chaldea, Persia, Tibet, India, etc., secretly cultivated a profound, hidden, and superior knowledge rejected and ignored by present day scientific dogma.  You will also learn how the modern Gnostic tradition is based upon the study and application of three esoteric sciences: Egyptian  الكيمياء‎ Alchemy, Hebraic קבלה Kabbalah, and Greek ψυχολογία Psychology or dialectics.  This lecture introduces these three sciences in accordance with the doctrines of Plato, Nietzsche, H.P. Blavatsky, Samael Aun Weor, and other philosophical and esoteric writers.
