1. Salutation to the lotus feet of my Guru Sri Sankarananda whose only work is to
destroy the monster of primal nescience together with its effect, the phenomenal
universe.
2. This discussion about the discrimination of Truth (Brahman) (from untruth) is
being initiated for the easy understanding of those whose hearts have been purified
by service to the pair of lotus feet of the Teacher.
3. The objects of knowledge, viz., sound, touch, etc., which are perceived in the
waking state, are different from each other because of their peculiarities; but the
consciousness of these, which is different from them, does not differ because of its
homogeneity.
4. Similar is the case in the dream state. Here the perceived objects are transient
and in the waking state they seem permanent. So there is difference between them.
But the (perceiving) consciousness in both the states does not differ. It is
homogeneous.
