As to the Mashriqu’l-Adhkár, it is of the utmost importance.… It may assume any form, for even if it be an underground pit, that pit shall become a sheltering paradise, an exalted bower, and a garden of delight. It shall become a centre wherein the spirits are gladdened and the hearts attracted to the Abhá Kingdom. 
- ‘Abdu’l-Baha  (Quoted by the Universal House of Justice in a message dated 18 December 2014, addressed to the Baha’is in Iran, authorized translation)
