" What is this thing we call form, and to what extent do we comprehend our own forms? I have a form, surely, as do you, and let us grant that we’re both conscious even though certain philosophers would argue that assertion—fortunately they’re not here. So! Both conscious. But we have imperfect knowledge of our own forms, let alone our own selves—consider the human man, his last self-image formed at the age of twenty-five, surprised by wrinkles on his forehead as he looks in the bathroom mirror. Deathless Kings’ residual physicalities endure long after they’ve become skeletons—and they perform premortem exercises to stem mental fragmentation. You’d be surprised how frequently and how widely mental image and physical form differ. "
