These are the words of don Miguel Ruiz. He is the author of the Four Agreements and The Mastery of Love. I don’t know which book they are from. Perhaps The Voice of Knowledge. The creator of this video didn’t seem to give a reference to the work. If these aren’t his exact words, then at least this is in alignment with his message.
These are the layers of the onion to be unraveled. To be free of your identity of the body. Then to be free of your identity of the mind. Then to be free to move beyond the Soul. To be life, the force that moves through all things. That is immortality. Life everlasting.
