Tanya Chapter 7 part 2. Elevating even the luxurious to holiness, like a sacrifice on the altar

Exploring kelipat nogah, the luminescent husk within the realm of impurity, which contains a mixture of good and holds the potential to be elevated to holiness or dragged into the depths of the three completely impure kelipot. Its destiny hinges on our intentions when interacting with the material world. When our focus is on serving Hashem, even the most luxurious items can be elevated to holiness, like a sacrifice on the altar. But when self-indulgence drives our actions, these objects are pulled deeper into spiritual obscurity, temporarily disappointing their potential.
