“… in this fleeting world - this burning house - all matters without exception are empty and false, totally without truth and sincerity. The Nembutsu alone is true and real."(Shinran Shonin, Tannisho)
If Namo Amida Bu/Namo Amida Butsu (Nembutsu) is true and real, then Amida Butsu is true and real. This is something that even children can understand. Namo means to entrust and take refuge in Amida Butsu (Amida Buddha). This refuge (Namo) is real and effective because the object of refuge – Amida Butsu – is true and real. Refuge in metaphors, symbols or fictional characters is not true refuge, but intellectual gymnastics.
