The Holy Spirit is the Boddhisattva

Rudolf Steiner, lecture 9 of "The East in the Light of the West," August 31, 1909:

The being who is the great teacher of all civilizations "is the totality of the Bodhisattvas. The Christian conception would designate it the Holy Spirit. The Bodhisattva is a being who passes through all civilizations, who can manifest Himself to humankind in various ways."
