Temenos:

A Greek word meaning a sacred, protected space; psychologically, descriptive of both a personal container and the sense of privacy that surrounds an analytical relationship.

Jung believed that the need to establish or preserve a temenos is often indicated by drawings or dream images of a Quaternary nature, such as mandalas.

The symbol of the mandala has exactly this meaning of a holy place, a temenos, to protect the center.

And it is a symbol which is one of the most important motifs in the objectivation of unconscious images.

It is a means of protecting the center of the personality from being drawn out and from being influenced from outside.[“The Tavistock Lectures,” CW 18, par. 410.]
