The source of truth comes from our inner self and the knowledge is subjective. The acquisition of subjective knowledge is based on intuitive thinking.
A little shimmer realized that there were many other shimmers who were much brighter than him. He tried to touch other shimmers because he wanted to grow brighter. He found that he was getting brighter when he touched others. But once he retracted his hands, he became dim again.
He swallowed other shimmers to keep the brightness. He became so insatiable that he swallowed everything with light. He became much brighter at first, but suddenly he was darkened because his body was gradually filled. And it was too full for him to vomit it.
After he spit out everything in his stomach, he found out that he was actually very shinning at the beginning.
