We have said before if something is infinite, we cannot establish if it gets bigger or smaller when divided; but all worldly matter, including the thickness of a sheet of paper, is finite. As such, matter will only get smaller and smaller when it is divided and eventually become empty.

By the same token, the feeling of happiness, the feeling of suffering, and so forth can also be broken down in this way until it disappears altogether into empty space.

- Quote from The Four Seals of Dhama, "The Practice of Realizing Emptiness"
