The Infinite life Sutra, the Contemplation Sutra and the Amitabha Sutra are the three principal sutras that Pure Land teaching is based on. No matter how profound and mysterious, or how simple and easy a presentation of the Pure Land teaching is, it should not violate the aim and objectives of the three sutras.
If there are violation and distortion, or slight deviation, it is not the Pure Land teaching anymore; it is a deviant, or even heterodox, teaching. The teaching principle of the three Pure Land sutras is not different from each other’s; they are the same and consistent. They all talk about the teaching of deliverance, not the teaching of cultivation. So, we must clearly grasp the main theme and meaning of the three sutras.
