The Buddhist teaching known as "Esho Funi" reveals that life and its environment are essentially one. This concept, which is of course a particular aspect of the general oneness of all things in the universe, gives us human beings great insight on how we should live our lives.
For example, if one arrives home after work in an angry mood because things have not gone well during the day it does not take long for this anger to permeate the entire household. Petty squabbles and bickering are very likely to occur in these circumstances. If we realise this and decide to put the problems of the day into their correct attitude. Those we meet will respond positively to our peaceful attitude. What a difference it makes!
Another important result of taking the teaching of Esho Funi to heart is that it becomes unthinkable to pollute our country or our planet in any way whatsoever for in doing so we are polluting our lives and the lives of all people including those we most love.
"If the minds of the people are impure, their land is also impure, but if
their minds are pure, so is their land. There are not two lands, pure and impure
in themselves. The difference lies solely in the good or evil of our minds".
-Nichiren Daishonin, the 13th century Japanese sage
