One of the Gnostic scriptures called "Pistis Sophia" contains many beautiful hymns and prayers. Though reincarnation is mentioned as a reality, the goal of salvation was to liberate souls from material captivity, reincarnation, the wheel of fate, and go back to God again. Souls were given the ability to mystically travel via the Holy Stream of Light. In Pistis Sophia (the Book of Faith-Wisdom) Christ says, "Seek, all of you, after the Light, so that the power of your soul that is in you may live. Do not cease seeking day or night until you find the mysteries of the Kingdom of Light, which will purify you, make you into pure Light and lead you into the Kingdom of the Light."
