The book, which often gives the description of the atman in hyperbolic terms, stresses that it can be realized here and now. Disciplines like renouncing the desires for the pleasures of life, cultivating virtues like forgiveness, kindness and truth are advocated. There is a beautiful description of the man of knowledge in the 17th chapter. Supreme detachment is a special characteristic of his. But it is difficult to recognize him since he often lives like an ordinary person. Only another man of knowledge can recognize him.
