" A disciple must understand purity correctly and the reasons why it is the key to health, joy, knowledge, power and eternal life. When you are pure, light can enter you more easily, and you begin to see and understand things more clearly. The diseased particles that undermined your health and your will are flushed out and your health improves and your will-power is strengthened. All darkness and obscurity depart and if you were sad you become joyful again, for joy is simply one aspect of purity. The more you purify yourself the more you will feel light-hearted, glad and happy. And as impurity leads to decay, disintegration and death, the purer you are the nearer you will be to immortality. All these things therefore – immortality, joy, happiness, knowledge, power and health – are simply different aspects of purity. This is initiatic science in a nutshell! It is up to you now to verify it for yourself! "
