Specific proportions can be observed in the genesis and creation of various forms existing in the nature. These proportions include that group of geometric relations that possess non-physical origins and they follow spiritual and metaphysical principles by believing in sacredness of subject and have a single symbolic language with spiritual features so they could be called sacred geometry.

As creator of structural form of spaces where humans live, architecture plays essential role in formation of their existential essence.
