182: SUMMER SCHOOLS (The Bahá'í)
 
1

"Definite courses should be given along the different phases of the Bahá'í Faith and in a manner that will stimulate the students to proceed in their studies privately once they return home, for the period of a few days is not sufficient to learn everything. They have to be taught the habit of studying the Cause constantly, for the more we read the Words the more will the truth they contain be revealed to us."
