Ordination is the process by which individuals are consecrated, that is, set apart as clergy to perform various religious rites and ceremonies. The process and ceremonies of ordination vary by religion and denomination. One who is in preparation for, or who is undergoing the process of ordination is sometimes called an ordinand. The liturgy used at an ordination is sometimes referred to as an ordination. 

The tradition of the ordained monastic community ("sangha") began with the Buddha, who established orders of monks and later of nuns. The procedure of ordination in Buddhism is laid down in the Vinaya and Patimokkha or Pratimoksha scriptures. There exist three intact ordination lineages nowadays in which one can receive an ordination according to the Buddha's teachings: 

Saicho repeatedly requested that the Japanese government allow the construction of a Mahayana ordination platform. Permission was granted in 822 CE, seven days after Saicho died. The platform was finished in 827 CE at Enryaku-ji temple on Mount Hiei, and was the first in Japan. Prior to this, those wishing to become monks/nuns were ordained using the Hinayana precepts, whereas after the Mahayana ordination platform, people were ordained with the Bodhisattva precepts as listed in the Brahma Net Sutra.
