What is the meaning of faith and nembutsu?

When one has faith (shinjin), one is convinced that Amida Buddha and His Pure Land exists, and that the Promise He made in His Primal Vow is true, so he simply entrusts to this Buddha and wishes to go to His Pure Land (Buddha-field of Amida) after death. Saying Namo Amida Bu often or seldom means exactly this – “I entrust to Amida Buddha/I take refuge in Amida Buddha and I wish to go to His Pure Land”. It also means, “Thank you Amida Buddha for saving me and taking me to your Pure Land at the end of this physical body”.
