And man has this plane of mind within him, below consciousness. In fact the lower forms of human life manifest but little Intellect, and live almost altogether according to their Instinctive impulses and desires. Every man has this Instinctive mental region within him and from it are constantly arising impulses and desires to perplex and annoy him, as well as to serve him occasionally. The whole secret consists in whether the man has Mastery of his lower self or not. From this plane of the mind arise the hereditary impulses coming down from generations of ancestors, reaching back to the cavemen, and still further back into the animal kingdom. A queer storehouse is this. Animal instincts--passions, appetites, desires, feelings, sensations, emotions, etc., are there. Hate, envy, jealousy, revenge, the lust of the animal seeking the gratification of his sexual impulses, etc., etc., are there, and are constantly intruding upon our attention until we have asserted our mastery. And often the failure to assert this mastery comes from an ignorance of the nature of the desire, etc. We have been taught that these thoughts were "bad" without being told _why_, and we have feared them and thought them the promptings of an impure nature, or a depraved mind, etc. This is all wrong. These things are not "bad" of themselves--they came to us honestly--they are our heritage from the past. They belong to the animal part of our nature, and were necessary to the animal in his stage of development. We have the whole menagerie within us, but that does not mean that we should turn the beasts loose upon ourselves or others. It was necessary for the animal to be fierce, full of fight, passionate, regardless of the rights of others, etc., but we have outgrown that stage of development, and it is ignoble for us to return to it, or to allow it to master us. This lesson is not intended as a discourse upon Ethics or morals. We do not intend going into a discussion of the details of "Right and Wrong," for we have touched upon that phase of the subject in other works. But we feel justified in calling your attention to the fact that the human mind intuitively recognizes the "Rightness" of the living up to that which comes to us from the highest parts of the mind--the highest product of our unfoldment. And it likewise intuitively recognizes the "Wrongness" of the falling back into that which belongs to the lower stages of our mentality--to the animal part of us, that is our heritage from the past and that which has gone before.
