Concerning the prerequisites of the learned, He saith: “Whoso among the learned guardeth his self, defendeth his faith, opposeth his desires, and obeyeth his Lord’s command, it is incumbent upon the generality of the people to pattern themselves after him....” [1]  Should the King of the Age reflect upon this utterance which hath streamed from the tongue of Him Who is the Dayspring of the Revelation of the All-Merciful, he would perceive that those who have been adorned with the attributes enumerated in this holy Tradition are scarcer than the philosopher’s stone; wherefore not every man that layeth claim to knowledge deserveth to be believed. 
- Baha'u'llah  (Tablet to Nasiri’d-Din Shah, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)
