As the study or science of things which are hid and secret, occultism is a generalizing term because what is hid or secret in one age may readily be in a succeeding age more or less commonly known and open to public investigation. Many things that in medieval Europe were distinctly secret and therefore occult, are today the field of scientific investigation; and what is now considered to be occult, if science continues in its progress and research, may in the succeeding age in its turn become open and matter of common knowledge. Occultism then will simply have shifted its field of investigation and study to matters still more secret, still more recondite, still more deeply hid in fields of nature which are now scarcely suspected.
Theosophy or the wisdom-religion is the study of the ancient wisdom of the gods, and comprises in any one period that particular portion of knowledge which has been delivered to those who study it; whereas occultism in any age is that portion of the ancient wisdom dealing with matters which at such time are secret, hid, and unknown to the multitude. Thus occultism is that portion of theosophy which has not yet been openly and publicly promulgated. Occultism is founded on the principle that Divinity is concealed -- transcendent yet immanent -- within every living being. As a spiritual discipline occultism is the renunciation of selfishness; it is the "still small path" which leads to wisdom, to the right discrimination between good and evil, and the practice of altruism.
