In plain words
A man whose Buddhi has no steadiness can never attain Śānti and happiness; for the deluded soul who runs after the pleasures of the senses, where is Śānti? Open your eyes and see, brother.

All religions have always taught one thing above all: purity of heart. They have taught that a man without that purity of heart gains nothing, however many kinds of sādhana he may do. When the dirt of Ahaṅkāra lies caked thick on the citta, how is purity to come to us? We can make the body clean with water. But if we want to make the heart pure, what is the substance we need for it? It is nothing but contemplation of the Name. The Name of God alone is the sacred substance that makes the heart pure. Prahlāda, born a demon, Jaṭāyu, a bird, and Gajapati, a beast, recognised their own divine nature through contemplation of the Name alone, and made their birth worthwhile. As long as Ahaṅkāra remained, neither Prahlāda nor Jaṭāyu nor the king of elephants could enjoy Śānti and joy. They were proud that they could put their own physical powers to use and win by those powers alone. In the end they came to see that physical strength and physical power are of no avail. Trusting that the strength of God is the real strength, and that the Name of God is the real strength, they prayed, ‘I know of none but You.’ In the court of the Kauravas, when they set about tormenting her in so many ways, who saved her? Draupadī’s husbands, mighty men indeed, powerful indeed, embodiments of Dharma indeed, were right beside her, and yet they could not end her torment. They could not ease her sorrow. Then she thought: no relative one has in this physical world can take sorrow away. When each one of them is sinking and crumbling under sorrows of every kind, how can such people end another’s sorrow? Every man is wasting away in some sorrow or grief of his own. How can a weakling who cannot shake off his own grief take away the griefs of others? One fruit cannot save another. Man can never take away man’s troubles. Some physical, worldly, passing troubles can be relieved a little, it is true; but troubles that go past all bounds, troubles that drive one out of one’s mind, only Mādhava can remove.
