" The law of Kia is its ever original purpose, undetermined, without change the emanations, through our conception they materialize and are of that duality, man takes this law from this refraction, his ideas-reality. With what does he balance his ecstasy? Measure for measure by intense pain, sorrow, and miseries. With what his rebellion? Of necessity slavery! Duality is the law, realization by suffering, relates and opposes by units of time. Ecstasy for any length of time is difficult to obtain, and laboured heavily for. Various degrees of misery alternating with gusts of pleasure and emotions less anxious, would seem the condition of consciousness and existence. Duality in some form or another is consciousness as existence. It is the illusion of time, size, entity, etc.-the world's limit. The dual principle is the quintessence of all experience, no ramification has enlarged its early simplicity, but is only its repetition, modification or complexity, never is its evolution complete. It cannot go further than the experience of self-so returns and unites again and again, ever an anti-climax. Forever retrogressing to its original simplicity by infinite complication is its evolution. No man shall understand "Why" by its workings. Know it as the illusion that embraces the learning of all existence. The most aged one who grows no wiser, it may be regarded as the mother of all things. Therefore believe all experience to be illusion, and the law of duality. As space pervades an object both in and out, similarly within and beyond this ever-changing cosmos, there is this secondless principle. "
