Translation
A person is said to be established in self-realization and is called a yogī [or mystic]when he is fully satisfied by virtue of acquired knowledge and realization. Such a person is situated in transcendence and is self-controlled. He sees everything—whether it be pebbles, stones or gold—as the same.
