A similar idea can be found in the Mahaprajnaparamita Sutra, which teaches that in helping others accomplish their enlightenment you accomplish your own. Where do we find people to help? In this world, and in every world in the ten directions, but mostly right in your immediate surroundings--your family, friends, colleagues, and especially, your adversaries, whom you should regard as bodhisattvas. Thus may the Pure Land exist on earth.
HOW TO ESTABLISH PEACE OR A PURE LAND ON EARTH-- THE METHOD
We have talked about the concept of a Pure Land on Earth, but how shall we accomplish it? The method we use we call the Three Practices, which consist of precepts (morality), meditation (concentration), and wisdom. I will discuss them in turn.
The precepts are the vows you take to lead a peaceful way of life through regulating your own behavior of body, thought, and speech. In the passive sense, upholding the precepts means vowing not to commit any wrongful acts. In the active sense, it means vowing to engage in as many acts as possible that benefit yourself as well as others; it means taking responsibility.
