Can the light in prayer be physically felt by some people, in addition to it being spiritual? If so, what are the ways to magnify this light, and what are its characteristics?

Prayer is light; it prevents sins and guides to righteousness. It will be a reward and a light for its performer on the Day of Judgment, and a cause for the radiance of the lights of knowledge and the expansion of the heart. Prayer is light in the heart, the face, the grave, and during the gathering (on the Day of Judgment), and its lights increase with its regular performance and devotion within it.
