Doubt

Doubt is not a sport to indulge in with impunity; it is a poison which drop by drop corrodes the soul.
One of the chief functions of the physical mind is to doubt. If you listen to it, it will always find a thousand reasons for doubting. But you must know that the physical mind is working in ignorance and full of falsehoods.
Cast away from you these movements of doubt, depression and the rest which are no part of your true and higher nature. Reject these suggestions of inability, unfitness and all these irrational movements of an alien force. Remain faithful to the Light of your soul even when it is hidden by clouds.

Anger

Anger is a violent reaction of the vital to some shock that is unpleasant to it; and when it involves words or thoughts, the mind responds to the influence of the vital and also reacts violently. Any expression of anger is the sign of a lack of self-control.
Anger, moreover, like all forms of violence, is always a sign of weakness, impotence and incapacity. Here the deception comes from the approval one gives it or the flattering adjective one covers it with; for rage can be no more than blind, ignorant and asuric—opposed to the light.
