The mysterious power in God's mention, in glorifying His praise

Consider this passage:

Blessed is the spot, and the house, and the place, and the city, and the heart, and the mountain, and the refuge, and the cave, and the valley, and the land, and the sea, and the island, and the meadow where mention of God hath been made, and His praise glorified.

- Bahá'u'lláh http://is.gd/5ztAo

What is there, actually, in such a heavenly "blessing"?
