"Lord Shima sent a messenger to his father, Lord Aki, saying, “I would like to make a pilgrimage to the Atago Shrine in Kyoto.” Lord Aki asked, "For what reason?" and the messenger replied, "Since Atago is the god of archery, my intentions are for the sake of fortune in war." Lord Aki became angry and answered. "That is absolutely worthless! Should the vanguard of the Nabeshimas be making requests to Atago? If the incarnation of Atago were fighting on the enemy’s side, the vanguard should just cut him neatly in two." Source: Tsunetomo, Yamamoto: Hagakure: Book of the Samurai.
