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

December 29

That which God — glorified be His Name! —hath desired for Himself is the hearts of His servants, which are the treasuries of His love and remembrance and the repositories of His knowledge and wisdom.  It hath ever been the wish of the Eternal King to cleanse the hearts of His servants from the things of the world and all that pertaineth thereunto, that they may be made worthy recipients of the effulgent splendours of Him Who is the King of all names and attributes.  Wherefore must no stranger be allowed in the city of the heart, that the incomparable Friend may enter His abode.  By this is meant the effulgence of His names and attributes, and not His exalted Essence, inasmuch as that peerless King hath ever been, and shall eternally remain, sanctified above ascent and descent. 
- Baha'u'llah  (Tablet to Nasiri’d-Din Shah, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)
