In plain words
So we must try to keep it within limits, teach it what is good and make it pure. Above all, we must see that the mind does not run after the pleasures of the senses. The mind falls into sorrow precisely when it spreads out over the senses. The mind is the husband of the senses. Living out one's life with one wife is itself hard going. What became of Daśaratha, who had three wives? There came parting from his son, and at the last the loss of his life in the very fire of longing for Rāma. Because Uttānapāda had two wives, he lost a good son like Dhruva, fell into many sorrows and at last gave up his life. When those with two or three wives met such a fate, what will become of the mind, which has ten wives?
The mouth asks its husband: ‘Husband! Bring me tasty dishes, or else I won't speak to you,’ it says. The ear: ‘Let me hear everything I want, or else I won't so much as look at your face,’ it says. Then the eyes: ‘Take me to some good exhibition; show me fine films, videos, televisions; if you don't, I won't stay at home.’ So they quarrel. In this way each sense voices its own desire and torments this mind in many ways. That is why the mind is forever sinking and wasting away in sorrow. The cause is nothing but the senses' influence. We must strive to keep the mind from turning towards these senses. We must try to keep the senses under our control. We must take care not to hand them everything they ask for. The mind must attain an independent place. The mind is the husband. The senses are the wives. Bhartā means the one who supports. The ones supported are the senses. Today, under the influence of the Kali age, the senses have turned into the supporters, and the mind, of all things, has become the one supported. The mind has come to this pass only by falling under the sway of the senses. Only when the mind inquires well, discriminates between the eternal and the transient and follows the Buddhi do the senses stay under control. Śrī Rāmacandra is the one who attained purity of thought, word and deed in this way.
Who is Śrī Rāma? If we think Śrī Rāmacandra is only the son of King Daśaratha, what benefit do we gain from remembering Him, from singing of Him, from meditating on Him? Who is Daśaratha? Daśaratha is nothing but the chariot of the ten senses: the five organs of action and the five organs of knowledge. This Daśaratha, the body, is ever joined with sattva guṇa, rajo guṇa and tamo guṇa.
