There are enlightened souls that live their lives with the knowledge of Oneness, and there are saints through which Oneness manifests itself. IF the heart neurons encode the pineal gland with an ‘observer’ code by  the 120th day of conception, ‘the observing one’ (Al-Baseer) will become manifest, potentially leading to sainthood;  otherwise Oneness remains only as a concept. The CONCEPT of Oneness is called Tawhid. The EXPERIENCE of Oneness is called UNITY (Wahdet). Statements like ‘I’ll be HIS eyes that see’, which insinuates a state of Observation, or ‘I’ll be the hand that holds’ define a state of UNITY. THE HUMAN is adorned with the knowledge of Oneness (Tawhid).
