December 13

Such is to be the restraint you should exercise that if you be made to quaff from the well-springs of faith and certitude all the rivers of knowledge, your lips must never be allowed to betray, to either friend or stranger, the wonder of the draught of which you have partaken. Though your heart be aflame with His love, take heed lest any eye discover your inner agitation, and though your soul be surging like an ocean, suffer not the serenity of your countenance to be disturbed, nor the manner of your behaviour to reveal the intensity of your emotions. 
- Baha’u’llah (Words of Baha'u'llah to some pilgrims and a few resident believers who were admitted into His presence on January 8, 1889, quoted by Nabil in the ‘Dawn-Breakers, translated and edited by Shoghi Effendi)
