Another small room, reached by a short ascent from the main floor [of the Celestial Room], is a vision of almost supernatural beauty. It is circular in form and resplendent in blue and gold, with borders and panels of red silk velvet. It is paved with an artistically designed native hard-wood mosaic, the blocks being mostly no more than an inch square, finely polished. From the dome which furnishes the ceiling, the light streams through seventeen circular and semi-circular jeweled windows, taking a thousand hues as, softened and subdued, it reaches the interior. The large art window to which the south side of this exquisite little room is given, is a work of surpassing loveliness. It represents the moment in the life of Joseph Smith when he, trusting in the words of the Apostle James, sought wisdom of the Lord, and received as an answer the visitation of two heavenly beings, one of whom, pointing to the other, said, "This is my beloved son; hear him!"....In these three small rooms last described the most sacred ordinances for the living and the dead are performed.
