The Holy Spirit
The Holy Spirit is the Creator manifesting Himself in the Creation through spiritual Adepts Who achieved full Self-realization (=God-realization) and merged into Him, and through Those Who have not entered into the Abode of the Creator yet but have achieved Mergence with the Holy Spirit.
The Holy Spirit supervises the activity of other spirits of earlier stages of evolutionary development. He also guides all successfully developing seekers, for example by giving them prophetic information. Jesus said the following about this: “But when He, the Spirit of Truth, comes, He will guide you into all truth. He will not speak on His own, He will speak only what He hears (from the Father and Jesus)…” (John 16:13).
Long before Jesus said these words, the Holy Spirit participated in the preparation of Jesus’ coming (Matt 1:20) by giving people miraculous signs about His special mission (Luke 2:25-35; 3:21; Matt 3:16); later the Holy Spirit took part in organizing Jesus’ work on the Earth (Luke 4:1).
