We should therefore attempt to remove all external impediments which are in the way of our spiritual development and live in a state of purity. Our thoughts should be continually directed inwardly and within ourselves; for within ourselves is the element of consciousness, knowledge, and power. Nothing hinders us to develop and exercise our own powers, except our misconceptions, imaginations, and external desires. Therefore the divine influences will only come to him who liberates his soul of all such hindrances, carnal desires, prejudices, and hallucinations. A diseased eye cannot bear to look at the light; an impure soul is repulsed by the divine light of truth.
Franz Hartmann, In The Pronaos of The Temple of Wisdom
