The realization of one's buddhanature is made possible only through an awakening to our limitations and inherent human imperfections. This paradoxical relationship is central to understanding the experience of awakening taught by Shinran Shonin ( 1173–1263 ), founder of Jodo Shinshu, or Shin Buddhism, the largest school of Buddhism in Japan and one of the oldest in America.
Shinran famously declared in the Tannisho (A Record in Lament of Divergences) that "hell is decidedly my abode whatever I do." This brutally honest assessment of himself and the human condition is a hallmark of Shrinran's thought; he posits awakening as a twofold awareness of one's own karmic evil (lack of buddhanature within oneself) and the working of the Buddha's great compassion, which embraces unconditionally enabling our enlightenment. Shinran's realization of his true inner self, which he perceived to be the exact opposite of an enlightened being, leads to his humbling confession of how he does not see the existence of buddhanature within himself, and yet, simultaneously awakens him to the activity of Amida Buddha's Primal Vow, which is inconceivably directed to him.
