These are the verses against materialistic Desires,wealth and pleasure in Upanishads.
The good is one thing; the pleasant, another. Both of these, serving different needs, bind a man. It goes well with him who, of the two, takes the good; but he who chooses the pleasant misses the end. O Nachiketa, after pondering well the pleasures that are or seem to he delightful, you have renounced them all. You have not taken the road abounding in wealth, where many men sink.I regard you, O Nachiketa, to be one who desires Knowledge; for even many pleasures could not tempt you away. (Katha Up 1.2.1-4)
The way to the future does not shine for the ignorant man who blunders, rendered, blind by folly caused by wealth; thinking thus ‘this world is and none other,’ be gets into my power(rebirth/death) again and again.(Katha Up 1.2.6)
The ignorant pursue external objects of desire; they get into the meshes of widespread death: but the intelligent, knowing sure immortality, do not covet the uncertain things here.(Katha Up 2.1.2)
When all desires clinging to the heart of one fall off, then the mortal becomes immortal and here attains Brahman.(Katha Up 2.3.14)
That which transcends hunger and thirst, grief, delusion, decay and death is your innermost Self. Knowing this very Self the Brāhmaṇas renounce the desire for sons, for wealth and for the worlds, and lead a mendicant life.(Brihadaranyaka Up 3.5.1)
