Initiation is a rite of passage ceremony marking entrance or acceptance into a group or society. It could also be a formal admission to adulthood in a community or one of its formal components. In an extended sense it can also signify a transformation in which the initiate is 'reborn' into a new role.

Examples of initiation ceremonies might include Hindu diksha, Christian baptism or confirmation, Jewish bar or bat mitzvah, acceptance into a fraternal organization, secret society or religious order, or graduation from school or recruit training.

A person taking the initiation ceremony in traditional rites, such as those depicted in these pictures, is called an initiate or initiand.

The English word derives from the Latin, initium: "entrance" or "beginning," literally "a going in." The related English verb, "initiate", means to begin or start a particular action, event, circumstance, or happening.

A spiritual initiation rite normally implies a shepherding process where those who are at a higher level guide the initiate through a process of greater exposure of knowledge. This may include the revelation of secrets, hence the term secret society for such organizations, usually reserved for those at the higher level of understanding. One famous historical example is the Eleusinian Mysteries of ancient Greece, thought to go back to at least the Mycenaean period or "bronze age".

Rudolf Joseph Lorenz Steiner (25/27 February 1861 – 30 March 1925) was an Austrian philosopher, social reformer, architect, and esotericist. Steiner gained initial recognition as a literary critic and cultural philosopher. At the beginning of the 20th century, he founded a spiritual movement, Anthroposophy, as an esoteric philosophy growing out of idealist philosophy and with links to Theosophy.

Steiner led this movement through several phases. In the first, more philosophically oriented phase, Steiner attempted to find a synthesis between science and mysticism; his philosophical work of these years, which he termed spiritual science, sought to provide a connection between the cognitive path of Western philosophy and the inner and spiritual needs of the human being. In a second phase, beginning around 1907, he began working collaboratively in a variety of artistic media, including drama, the movement arts (developing a new artistic form, eurythmy) and architecture, culminating in the building of a cultural centre to house all the arts, the Goetheanum. After the First World War, Steiner worked with educators, farmers, doctors, and other professionals to develop numerous practical initiatives, including Waldorf education, biodynamic agriculture, anthroposophical medicine.
