House of Worship benefits - assists in teaching

(Quotations on the House of Worship as a Silent Teacher)

""Silent Teacher" is associated with the functions of diffusing the knowledge of His Faith and Teachings, the propagation of the Cause, spreading the Cause, promoting the Teachings. [3,4,7,8,9,10,15]"

A centre (ideally a Mashriqu'l-Adhkár to be built there in the future) to be set aside for the teaching work and the delivery of talks

"In these days one of the essential requirements of the Faith which will attract divine blessings and lead to the protection of the servants at His Threshold, is to set aside a suitable place to serve as a centre for Bahá'í activities in each of the localities where believers reside. In such a centre, even if it is among the most modest of locations, all gatherings of the friends should be held, such as those for the reading of the Tablets, for prayers and supplications, for the meetings of the Local Spiritual Assembly, for the teaching work, for the delivery of talks, for commemorations, for festivals and for the Feasts. If the location is suitable, it would be light upon light if in the future the edifice of the Mashriqu'l-Adhkár could also be erected on that spot. That centre should be named Hazíratu'l-Quds, so that the musk-scented breaths of the fervent prayers offered therein, and the sweet breeze of spiritual discussions and worthy enterprises wafted from the Hazíratu'l-Quds may spread to neighbouring regions, and impart healing and fragrance to the nostrils of a sorely-afflicted world."
