Regarding the Mashriqu’l-Adhkar, ‘Abdu’l-Baha said:
Its building is the most important of all things. This is the spiritual foundation. For that reason it is the most important of all foundations. From that Spiritual Foundation will come forth all manner of advancement and progress in the world of humanity. Therefore, how great is its importance.
Later on ‘Abdu’l-Baha said:
The believers have many duties to perform. They should associate themselves with and assist all good causes. Aiding and supporting educational, charitable and other philanthropic institutions should form a part of their work. They should serve and unite with all people in humanitarian works.
