There is an experience which grows in the soul out of the soul itself, without contact and without restraint, in naked oneness. It comes into being and completes itself beyond the commotion, free of the other, inaccessible to the other. It needs no nourishment, and no poison can touch it. The soul which stands in it stands in itself, has itself, experiences itself - boundlessly.
Crystal clear, sharp and bright, my mind has no opening for evil to roost. The morning sun shines in, My mind, too, is clear and bright;
It pervades the entire universe but nothing pervades it. It is effulgent by nature, and its splendor illumines everything...
i thank You God for most this amazing day: for the leaping greenly spirits of trees and a blue true dream of sky; and for everything which is natural which is infinite which is yes
This is an account written by Norris Stearns of Greenfield, Massachusetts, published in 1815, five years before Joseph Smith's First Vision experience, in a pamphlet titled The Religious Experience Of Norris Stearns Written by Divine Command. The 35 page pamphlet can be read in its entirety online at this link. Here is an excerpt of part of his vision.
"As I wander through the dark, encountering difficulties, I am aware of encouraging voices that murmur from the spirit realm. I sense a holy passion pouring down from the springs of Infinity... Bound to suns and planets by invisible cords, I feel the flame of eternity in my soul. Here, in the midst of the every-day air, I sense the rush of ethereal rains. I am conscious of the splendor that binds all things of earth to all things of heaven—immured by silence and darkness, I possess the light which shall give me vision a thousand-fold when death sets me free."
"Sometimes in meditation I experience deep silence, being in an unbounded empty space. Sometimes I see light in that empty space like the sun."
"One day during my [meditation] my head became full of light and the room was full of sunlight (and yet it was totally cloudy outside). It was beautiful. I felt healed, safe and full of nature's forgiveness. After meditation I lay down for a few minutes and I felt as if I was lying gently in heaven's cradle."
