The promise of Jesus to send the Holy Ghost after he was gone few in the Christian world have understood. Holy Ghost is the sacred, invisible vibratory power of God that actively sustains the universe: the Word, or Aum, Cosmic Vibration, the Great Comforter, the Saviour from all sorrows. Within the Holy Ghost Cosmic Vibration is the all-pervading Christ, the Son or Consciousness of God immanent in creation. The method of contacting this Cosmic Vibration, the Holy Ghost, is for the first time being spread worldwide by means of definite meditation techniques of the Kriya Yoga science. Through the blessing of communion with the Holy Ghost, the cup of human consciousness is expanded to receive the ocean of Christ Consciousness. The adept in the practice of the science of Kriya Yoga who consciously experiences the presence of the Holy Ghost Comforter and merges in the Son, or immanent Christ Consciousness, attains thereby realization of God the Father and entry into the infinite kingdom of God.
