Light, color, and geometry have always had a special place in mysticism and art, especially in architectural and decorative arts-- as t main component of architectural art. Decorative arts, despite their enchanting and beautiful appearance, are not limited to a decorative aspect. To understand them, one should be familiar with the mystical concepts of light, color, and geometry as well. The Iranian artist is aware of these features and his intelligent use of them in creating works of art has made him create lasting and impressive works. The main goal of this research is to introduce the art of stained glass with a regard to the influence of the mysticism of light and color. Furthermore, it tries to discuss how the glass design of the sashes used in the Western Shabestan of the Nasir al-Molk Mosque can be used in interior decorations and handcrafts can ooze relaxation and positive feeling.  . To this end, ancient Iran's optical wisdom, illumination wisdom, colors and their mystical meanings, glass, its history, and the way it was made were discussed. Besides, the art of sash-making in Nasir-ul-Molk Mosque, and its sashes were studied. The deployed method was descriptive-analytical, and data were collected through library and field study.  The findings of the present research showthat by combination of Iranian mystical attitudes and trends with the knowledge and of making, designing, and using glass and related arts, one can preserve the national material and spiritual heritage and devote himself to the revival of this Iranian art, which is a combination of art, science, and mysticism.
