Everything in the universe have three common properties: anicca, dukkha, and anatta. People, animals, things, towns, mountains, planets, stars, joy, money, knowledge, memories, everything you may imagine, everything you can't imagine. Every possible thing is anicca, dukkha, anatta. These three words are Pali words (Pali was the language spoken by the Buddha).

The word "buddhism" derives from "buddha". The one called "Buddha" is someone who has discovered nature of things as they are (among the whole of existing : life , universe, etc.) His was the only one able to understand completely and by himself all the life process: "Buddhism" is then Buddha's teaching, it is the way he suggests us to follow.
