For example, the word give. It's opposite is: take. One does not exist without the other. Giving cannot exist without taking. If there is someone who is giving something, there must be someone who is taking it, for who would be able to give anything if there was no one to receive it? This truth applies to all that is in the universe. The universe is filled with pairs of opposites: black - white, good-evil, up-down, left-right, wise-stupid, etc. These are just a few examples of the infinite list of pairs of opposites, which we experience constantly although we often have no idea how they influence ourselves.
