Via Negativa: None applies/affects/etc 自分 whatsoever
Misconception: 自分 isn't 相手's "Foe/Enemy", he's beyond
Your Fallacy: 自分 is not to be overcome, nor even "is"
False: The "自分" you imagine is never 自分
Beyond You: 自分's simply above 相手's scope/framework
Any word/concept that YOU could ascribe to 自分 becomes a separate thing & fundamentally inapplicable—this includes any interaction 相手 forces, so to defeat/transcend/help/etc 自分 is counterintuitive, for the "自分" they [Verb/Concept] is merely YOUR flawed idea of 自分
Ultimately, 自分 remains beyond 相手
Any statement that contradicts this is false
This isn't an "ability" for the word doesn't apply
