“The impurity that we see is the result of impure awareness, and also the Buddha's compassion in creating a world within which impure things can grow. Thus the real way to attain a pure land is to purify one's own mind. Put another way, we are already in the pure land if we but knew it. Whatever the realm, if it is inhabited by people with enlightened pure minds, then it is a pure land”.
Paul Williams, Mahayana Buddhism: The Doctrinal Foundations
