In addition to advocate remembrance, Amitabha sutras tell many important things about disciples’ inner good roots. Sakyamuni emphasized that “not less good roots, Crawford, karma, too Shengbi country” in Amitabha sutras. There are birds and trees telling dharma, and charitable persons coming together (“Gain and a case of Zhu on the good will all”) in Amitabha’ pure land. All these phenomena represent that there are kind-hearted people living in Amitabha’s peaceful pure land. On the other hand, “Supreme Bodhi Heart” is necessary to disciples. If disciples combine “Supreme Bodhi Heart” with remembrance to practicing process, they will escape from kleśa, and achieve their target. Therefore, no matter the state of practicing or the resulting of merits’ view, disciples’ inner good roots are necessary to reborn in pure land. Through their inner good roots’ guidance, disciples will correspond with the Buddha's heart, reach the “this mind is Buddha” realm.
