May 2

Verily, this is the Remembrance that hath shone forth above the horizon of creation, which shall purge thy soul from the dross of the world. Abandon thy palaces to the people of the graves, and thine empire to whosoever desireth it, and turn, then, unto the Kingdom. This, verily, is what God hath chosen for thee, wert thou of them that turn unto Him… Shouldst thou desire to bear the weight of thy dominion, bear it then to aid the Cause of thy Lord. Glorified be this station which whoever attaineth thereunto hath attained unto all good that proceedeth from Him Who is the All-Knowing, the All-Wise. 
- Baha'u'llah  (Tablet to Napoleon III, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)
