In this process of energising will and creating Life, a part of the knowledge loses itself. Hence, the plane of Life is less conscious than the plane of Mind. Involution continues and knowledge continues to work on Force and loses itself entirely, at which point Force becomes Matter. Thus the plane of Matter is generated. Involution does not cease till knowledge is fully lost in Matter, which means the origin of knowledge-consciousness becomes the Inconscient.
Involution goes further.
That which is prior to consciousness i.e., the Being, also loses itself in the process into its opposite, Non-Being. Now that the Involution is complete, Being that has self-concealed itself has come to the point that it forgets the very fact of losing itself. Being must remember Itself, which is awakening, in order to start the reverse process of evolution. Evolution is the emergence of Light from Darkness, Knowledge from Ignorance and Good from Evil. It is clear that Ignorance is a later product than knowledge, Darkness than Light, Evil than Goodness.
