A Master-Key to the Mysteries of
Ancient and Modern Science and Theology
Helena P. Blavatsky
Helena P. Blavatsky (1831-1891)
Volume I – Science
A 2017 Editorial Note:
First published in 1877, “Isis Unveiled” is a true
masterpiece of esoteric philosophy and will remain so.
It was written with the direct cooperation of immortal
sages. Its outward imperfections belong to that denser crust
which is necessary to protect the substance of eternal wisdom.
(Carlos Cardoso Aveline)
