115 Ignorance, laziness, drowsiness, sleep, carelessness, stupidity and so on are the effects of the dullness quality. One stuck in these does not understand anything, but remains as if asleep, like a wooden post. 116 Clear purity is like water, but combined with these other qualities it leads to samsara, though in this purity the nature of the self is reflected, like the disk of the sun illuminating the whole world. In purity mixed with the other qualities virtues such as humility, restraint, truthfulness, faith, devotion, desire for liberation, spiritual tendencies and freedom from entanglement occur. In real purity however the qualities which occur are contentment, self-understanding, supreme peace, fulfilment, joy and abiding in one's supreme self, through which one experiences real bliss.
Deep sleep is a special condition of it, in which the activity of all functions of awareness cease.
120 Deep sleep is the cessation of all forms of awareness, and the reversion of consciousness to a latent form of the self. The body, its functions, vital energies, the thinking mind, etc., and all forms, objects, enjoyment, etc. Everything is the creation of Maya from space itself down to the individual body. Look on it all as a desert mirage, unreal and not yourself. Now I will instruct you in the true nature of your supreme self, by understanding which a man is freed from his bonds and achieves final fulfilment.
