This means:
Whether in village or in forest, in vale or on hill, wherever Arahants dwell, - delightful indeed, is that spot.
According to Buddha mental vibration has powerful effect in making the environment delightful. Only making good environment physically is not sufficient, people inhabitants should also possess good mentality in order to make the place delightful. One can't live happily and peacefully at that place if the majority of people there are full of anger, hatred and illusions. But people even with full of tension can feel happy and peace if the place is full with loving kindness, compassion, sympathetic joy and equanimity. In this way a person with good mentality can contribute for the good environment in the society.
Conclusion
In this way good environment is the aggregate of both physical as well as mental environment. Only protection of physical environment is insufficient and not a complete protection of environment. In Buddha's teachings there are several discourses of protection of not only of physical environment. It also has focused on the need of protecting mental environment. Buddha's teachings if is securitized properly it reveals the protection the society from the pollution that could be from the Kaya (body), Vacana (speech), and Mana (mind). Buddha had inspired to make good environment because it helps to get success in social life, economic life and spiritual life. If the teachings of Buddha are propagated properly the problem of environmental destruction can be minimized significantly.
