束縛状態を解放に向けての行い(小鳥を放つ)は、仏教で殺生を諌めるため、生物を放つ習わしがあり、その際にハトを使う。また、囚われた一羽の鳥を野に放つ行為は、キリストの復活を象徴する。中国では鳥を放つと幸運が訪れると言われ、祭事、祝い事にハトを放つ習慣がある。これらのことが発展、展開して、今日では各行事で平和の証しとしてハトが放たれている。


An act of liberation from bondage (releasing a bird) has been practiced to embody the Buddhist teaching not to kill the living things. Very often doves are used for this. In Christianity, releasing a captured bird into the field symbolizes the Resurrection. In China, it is believed that releasing a bird attracts good fortune and traditionally they release doves on festivities and celebratory occasions. Having evolved from these traditions and customs, today doves are released in various events as a pledge for peace.
