In Farid al-Din Attar's 'The Tale of the Moon and Its Yearning for the Sun' from the Elahi Nameh, the moon's desire to reach the sun and its subsequent disappearance in the sun's overwhelming light serves as an allegory for the Sufi concept of spiritual annihilation (fana). The poem illustrates how the seeker, much like the moon, must endure the burning of their own existence and ego in the blinding radiance of the Divine (the sun). This state of being 'under the rays' represents the ultimate union with the Beloved, where the individual self is entirely effaced, becoming invisible and consumed by divine majesty.
