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

May 9

O Vafa! [1]… It behoveth thee, however, to exert thine utmost to attain the very essence of fidelity. This implieth to be well assured in thy heart and to testify with thy tongue to that whereunto God hath testified for His Own exalted Self, proclaiming: ‘Verily, self-subsisting am I within the Realm of Glory.’ Whoso is enabled in these days to solemnly affirm this truth, hath attained unto all good, and the heavenly Spirit shall descend upon him in the daytime and in the night season, shall graciously assist him to glorify the Name of his Lord and suffer him to unloose his tongue and uphold with his words the Cause of his Lord, the Merciful, the Compassionate. And none can ever achieve this except he who hath purged his heart from whatsoever is created between heaven and earth, and hath entirely detached himself from all but God, the sovereign Lord, the Almighty, the Gracious. 
- Baha’u’llah  (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)
