Buddha -- himself the holy spirit enters into Queen Maya as a beautiful pure white elephant.
Buddha himself is called in the Tipitika as "Brahma Bhuto", Bhuto literally means "Ghost" or "spirit",
Brahma means "divine creation" -- literally, Buddha himself is the divine holy Ghost.
Speaking against the Buddha, according to the New Testament would be the greatest sin --- an unforgivable sin!
The Holy Ghost is that which is free of all material defilements, to blasphemy this Holy Spirit is to blasphemy purity.
The Holy Spirit enters Jesus as a Dove (Gospel of John).
Mt. 12:31-32 And so I tell you every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will
not be forgiven. Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy
Spirit will not be forgiven, either in this age or in the age to come.
Buddha is the Holy Spirit:
Tathagatassa hetam, adhivacanam brahmabhuto itipi-The Tathagata root meaning, 'the body of Brahman', 'become Brahman'
[DN 3.84]. (brahmabhutam tathagata)-Become-Brahman is the meaning of Tathagata [It 57]
He whose faith in the Tathágata is settled, rooted, established, solid, unshakable by any ascetic or Brahmin, any deva
or mara or Brahma or anyone in the world, can truly say: "I am a true son of the Blessed Lord, born of his mouth, born
of Dhamma, created by Dhamma, an heir of Dhamma." Why is that? Because, Vasettha, this designates the Tathágata: "The
Body of Dhamma[dhammakayo]," that is "The Body of Brahma[brahmakayo],"  or "essence (spirit) of Dhamma,"
that is "spirit (essence of Brahma (Brahma is the expansive spirit underlying matter and it's formations, but beyond
matter and therefore pure).[brahmabhuto]," - that is the true meaning of the Holy Ghost.
