In plain words
We feed these horses as they please, fatten them, and raise them so that they grow wild with pride. That is why these horses, wild with pride, take the wrong road and plunge their very master into danger. So we must use our senses according to what God has fixed for them. If we do not use them in the right way like this, they fall into unrest of many kinds.
Many know this. Even with one wife a household is troubled. With two wives, there is no need to say more. Uttānapāda had two wives. That is why so many differences arose there that his own son Dhruva had to be sent into the dense forest. Daśaratha had three wives. He too, because these differences made it impossible to keep them on good terms, and because he meant to make his wife happy, sent his own son Śrī Rāma to the forest and lost his life. If with just one or two wives so many troubles arise, think how much trouble those with ten wives fall into. This great man called the Manas has ten wives: those very wives are the ten senses. Each sense keeps wanting something of its own. One sense, the nose, says: 'There is a smell of masālā; I want a masālā dosa.' The ears say: 'I want to hear sweet music; put on the radio.' 'Some new film has come out, they say; I must see it,' the eyes long. In this way each sense goes on asking for something of its own. When all at once each sense has its desire, how can this master satisfy that desire? So, unable to satisfy the desires of the senses, the Manas collapses in many ways. Where is Śānti to come from for this master called the Manas, who has so many wives? Śānti stays very far away. The reason is that satisfying the cravings of these senses is very hard. So only when we bring the nature of these senses under proper control can a person and the people around him too enjoy happiness.
Yet there is also a way of bringing the senses into harmony.
