The sense-minds and their centralised discriminating-mind are related to the external world which is a manifestation of itself and is given over to perceiving, discriminating and grasping its maya-like appearances. Universal Mind transcends all individuation and limits. Universal Mind is thoroughly pure in its essential nature, subsisting unchanged and free from faults of impermanence, undisturbed by egoism, unruffled by distinctions, desires and aversions. Universal Mind is like a great ocean, its surface ruffled by waves and surges but its depths remaining forever unmoved. In itself it is devoid of personality and all that belongs to it, but by reason of the defilement upon its face it is like an actor and plays a variety of parts, among which a mutual functioning takes place and the mind-system arises. The principle of intellection becomes divided and mind, the functions of mind, the evil out-flowings of mind, take on individuation. The sevenfold gradation of mind appears: namely, intuitive self-realization, thinking-desiring-discriminating, seeing, hearing, tasting, smelling, touching, and all their interactions and reactions take their rise. The discriminating-mind is the cause of the sense-minds and is their support and with them is kept functioning as it describes and becomes attached to a world of objects, and then, by means of its habit-energy, it defiles the face of Universal Mind. Thus Universal Mind becomes the storage and clearing house of all the accumulated products of mentation and action since beginningless time.
