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

April 21

This is the Day whereon the unseen world crieth out: “Great is thy blessedness, O earth, for thou hast been made the footstool of thy God, and been chosen as the seat of His mighty throne.” The realm of glory exclaimeth: “Would that my life could be sacrificed for thee, for He Who is the Beloved of the All-Merciful hath established His sovereignty upon thee, through the power of His Name that hath been promised unto all things, whether of the past or of the future.” This is the Day whereon every sweet smelling thing hath derived its fragrance from the smell of My garment—a garment that hath shed its perfume upon the whole of creation. This is the Day whereon the rushing waters of everlasting life have gushed out of the Will of the All-Merciful. Haste ye, with your hearts and souls, and quaff your fill, O Concourse of the realms above!
