A Religion is a set of beliefs that is held by a group of people. There are many different religions, each with a different set of beliefs. The beliefs are about the world and the people in it, about how they came into being, and what their purpose is. These beliefs are often linked to supernatural beings such as God, a number of gods or spirits. They may also be linked to an idea such as a path that the spirit of each person should take towards goodness, truth and duty. This is called spirituality. Each religion has different ideas about these things. Each religion also has a "moral code" which is a set of beliefs about how humans should act. Each religion usually has their own type of "devotions" when people worship or pray. They often have rituals (special things that are always done in the same way) for certain times of the year or certain times of a person's life. Other words that are used for religion are "faith" and "belief system". Altogether, followers of religion can be known as religionists. Some people follow more than one religion at a time.
The largest religions are Christianity, Islam, Hinduism, Buddhism, Taoism, Sikhism and Judaism. There are many other religions. People who do not believe in any gods are called atheists. People who say that they are not sure whether they believe or not are called agnostics.
