In plain words
We must not set about giving the tongue everything it asks for. When we set about satisfying it, in the end we cannot bring it contentment. Here is an example of this. So that we may shape our life to be radiant, beaming and laughing merrily, we give it butter, creamy milk, fruits, special strengthening foods like these, we give them to it; and by doing so, in the end all those who are the tongue's friends, kāma, krodha, lobha, moha, Ahaṅkāra, envy and the rest, become the tongue's closest friends. The reason is that, because great comfort and ease are to be had in the tongue's home, the tongue sets about inviting its friends, thinking that pleasure will be had easily. So we cannot help saying that the root cause for our senses is the tongue alone. We keep only the taste in view, but we do not stop to consider how much our life is going to waste. Every single bit of food we take turns, in its gross form, into excrement and urine and goes out as matter at odds with the world. Then, in its subtle form, the food itself turns into blood and muscle. And this food, at its most subtle, turns into the mind. So our food itself appears as the root cause, whether of the distortions of our mind or of its purity. That is precisely why the Veda has been teaching us that food is the chief principle for developing good qualities such as supreme calm, patience, courtesy, Prema and Satya. Bhāratīya Vedānta has been showing sāttvic food, or what goes by the name of control of the senses, to be the fitting doorways to the attainment of Mokṣa. For a man who cannot master the senses themselves, there is no happiness and Śānti, not in this world alone, but in any other world whatever, too. Not only do they keep happiness and Śānti from us; these agitations of the senses take away our honour and good name as well. To that end, all our ṛṣis of Bhārata from time beyond reckoning, every one of them, took on silence, ate sāttvic roots and tubers, lived on roots, drank flowing water, and so set about offering their noble citta to God.
