“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

May 21

This is a remembrance of that which was revealed in the year sixty in the days of God, the Almighty, the Help in Peril, the All-Glorious, the All-Knowing.

Lo, the gates of Paradise were unlocked, and the hallowed Youth came forth…Upon His shoulders there fell the locks of the spirit, like unto black musk upon white and lustrous pearls. Rejoice! This is the immortal Youth, come with a transcendent cause.

On His right hand was a ring adorned with a pure and blessed gem. Rejoice! This is the immortal Youth, come with a mighty spirit.

Upon it was graven, in a secret and ancient script: “By God! A most noble Angel is this.” [1] And the hearts of the inmates of the eternal realm cried out: “Rejoice! This is the immortal Youth, come with an ancient light.”
