天心流兵法 柿生支部より、小太刀抜刀術の灯火剣。
別名を冥暗送(めいあんおくり)と言います。
抜刀で両眼を切り、蛇体の位となり、切り損じた場合は再び前に出て、左手にて顔を鷲掴みにしつつ刃を押し当てて引き切ります。
両眼を蝋燭の火に喩えるので灯火剣(とうかけん)、また暗闇、すなわち冥府の暗闇に送るという程の意味から、冥暗送と呼びます。
これは見せしめの剣であり、殺さないという意味では活人剣に含まれます。
"Tokaken (灯火剣)~Meian-Okuri(冥闇送)"
This is a technique to cut both eyes.
First cutting aims enemy's eyes.
If I can cut both eyes safely, it is done. However, if first cutting is failed, I try to do second cutting with left hand and make the enemy "blind".
冥暗 means "darkness", and 送 means "dispatch", so we dispatch the enemy to dark world.
This is a technique not to kill.
The technique punish him as a warning to the other everyone.
Therefore, it is also included in Katsujinken(活人剣) in a broad sense.
