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

March 15

O people! Deal not faithlessly with the Right of God, nor, without His leave, make free with its disposal. Thus hath His commandment been established in the holy Tablets, and in this exalted Book. He who dealeth faithlessly with God shall in justice meet with faithlessness himself; he, however, who acteth in accordance with God’s bidding shall receive a blessing from the heaven of the bounty of his Lord, the Gracious, the Bestower, the Generous, the Ancient of Days. He, verily, hath willed for you that which is yet beyond your knowledge, but which shall be known to you when, after this fleeting life, your souls soar heavenwards and the trappings of your earthly joys are folded up. Thus admonisheth you He in Whose possession is the Guarded Tablet. 
(Baha’u’llah, ‘The Kitab-i-Aqdas’)
