The two best known religious actions are prayer and sacrifice. The most general religious action is prayer. It can be done quietly by a person all alone, but people can also pray in groups using songs. Sacrifice is also a widely spread religious action. Prayer and sacrifice often form the basis of other, more complicated religious actions like pilgrimage, processions, or consulting an oracle. Many rituals are connected to a certain purpose, like initiation, ritual purification and preparation for an important happening or task. Among these are also the so-called rituals of transition, which occur at important moments of the human life cycle, like birth, adulthood/marriage, sickness and death. A special religious action is spirit possession and religious ecstasy. Religious specialists, such as priests, vicars, rabbis, imams and pandits are involved in many religious actions.
A religious avoidance is when a person desists from something or from some action for religious reasons. It can be food or drink that one does not touch because of one's religion for some time (fast). This abstinence can also be for a longer time. Some people do not have sex (celibacy). Or one avoids contact with blood, or dead animals. Well known examples are: Jews and Muslims do not eat pork; the celibacy of Catholic priests; the purity rules of Hinduism and Judaism.
These avoidances, or 'taboos', are often about food and drink.
Religious avoidances are often not easily recognisable as (part of) religious behaviour. When asked, the believers often do not motivate this kind of behaviour explicitly as religious but say the avoidance for health reasons, ethical reasons, or because it is hygienic.
Religious behaviour is seldom studied for itself. When it is given attention at all, it is usually studied as an illustration of the religious images, like in comparative religion and cultural anthropology, or as part of the study of man in the social sciences.
