This fallacy says that people mistakenly believe that children are connected to the Divine in a similar way as those mystics who transcend ego. I don't think this is mistaken at all.
Many mystical paths in the world's spiritual traditions claim to lead one to a conscious merging, union, and a direct identification with Deity, the Sacred, Reality, the Universe, the Transcendent, with a first-hand experience of being God.
"Sometimes during meditation golden light pours into my head, as if squeezed through a cloth, filling my head with light. At times, I feel like a newborn baby entering a new dimension of reality made of infinite tenderness, purity, love, and divine wholeness, a heavenly domain."
