The sage, contemplating the non-difference of objects, actions and conceptions, destroys the three states of ignorance—concerning objects, actions and conceptions-- by his realization of ātmā. Now the philosophy of advaita is made firm by teaching about the three states of perception. This is explained in four verses. Considering non-difference in thought, action and objects with the self, by realization of ātmā, the sage destroys differences in the form of three types of sleep. One sleep is thinking of differences between objects. The second sleep is thinking of different activities for differently qualified persons. The third sleep is thinking that what I receive as a result of action belongs to me.
