The Holy Ghost/Spirit is Christ' Spirit

The Holy Ghost/Holy Spirit is not a female and it's not Jesus's mother. The Holy Spirit is the Spirit of the Son, that's why Jesus likened himself to a seed falling to the ground and dying in order to be fruitful. Jesus died on the cross, was resurrected, ascended to heaven and sent his Spirit back to dwell in his people. As a man, he was limited by being in one place at a time, but as the Holy Spirit, he can dwell in all his people and lead all of us at the same time, dealing with everyone on their level until we all are on the same level.
