Before taking up our subject as outlined at the close of the previous volume, I would like to speak a word as to the symbolism we will employ in discussing egoic and personality control. All that is said in this connection is in an attempt to define and consider that which is really undefinable and which is so elusive and subtle that though we may call it energy or force, those words ill convey the true idea. We must, therefore, bear in mind that, as we read and consider this treatise on psychology, we are talking in symbols. This is necessarily so, for we are dealing with the expression of divinity in time and space, and until man is consciously aware of his divinity and demonstrating it, it is not possible to do more than speak in parable and metaphor with symbolic intent - to be ascertained through the medium of the mystical perception and the wisdom of the enlightened man.
