「初学者のための、21日で学ぶ歎異抄」は、歎異抄を初めて読む人に向けた学習アプリです。 序文から後序までを一日一条の形式で読み進め、原文、やさしい解説、図解、確認クイズを通して、少しずつ理解を深めていきます。 歎異抄は、親鸞の教えをめぐる誤解を歎き、聞き残された言葉を伝える書物として読まれてきました。短い言葉の中に、他力、本願、念仏、悪人正機、信心など、浄土真宗の大切なテーマが込められています。 このアプリでは、難しい専門語をいきなり暗記するのではなく、毎日の講義を通して「自分の言葉で受け止める」ことを大切にしています。 主な機能: - 21日間で序文から後序まで学べるカリキュラム - 初学者向けのやさしい解説 - 原文表示と難読語のふりがな - 重要語をその場で確認できる用語解説 - 各回の確認クイズ - 完了済みクイズからの復習 - 今日の問いに答えるメモ機能 - 次回講座の解放通知 - 復習通知 一度に多くを詰め込むのではなく、毎日ひとつのテーマに向き合うためのアプリです。 歎異抄を読んでみたいけれど、どこから始めればよいかわからない方。 浄土真宗の言葉を、暮らしの中で少しずつ学びたい方。 原文と解説を行き来しながら、落ち着いて読み深めたい方におすすめです。
