If a person looks at a cup with nothing in, they say its empty. If you could not see it, you wouldn't know. To describe this observation, a person uses the word 'empty'. But nothing is empty. It saves us from saying "this cup is full of air"

If this is the emptiness in Buddhism, it means nothing is empty. In other words, this explains that everything is full.
But fullness is not the opposite of emptiness in Buddhism. So please lets give the real meaning. If emptiness is merely a word then it must have an opposite for sure...
