I replied, "bread and love exist at the same time." Bread represents material needs, which is a low-level demand to meet your physiology, while love represents spiritual needs, which is a high-level demand. We can have love, but we can't enjoy it better without bread. This is similar to the material basis and spiritual level. With a good material foundation, we can better enjoy the spiritual world. And bread is the foundation, because we can't talk about love on an empty stomach. Only when the foundation is laid can any good spiritual enjoyment be satisfied. However, matter is the only force that supports the spirit. How can we talk about spirit if we can't satisfy the material? So love is based on material things.
