I feel, This inspiring story is to be added in this topic. It may suggest highest level of morality or validity or justification:
Once, one GOD at basic level preferring natural living was getting married. Many competent angels came to greet and gift HIM.
One Angel A competent in building/city making asked: "O great Lord, since you are getting married, you shall need a house. I shall made a big & beautiful palace for you having maximum needed facilities".
God asked: "for how much time your house will sustain and will it give all nature like facilities?
Angel A: House will be sustainable for about 100 years but it can not provide all nature like facilities.
God: Then why I should take it, when I have this consistent permanent nature house all around with all nature facilities? Why I should opt an inferior thing against superior thing?
Angel A: Awnserless.
Then Angel B competent in wealth asked: O Lord, your wife will need so many ornaments and wealth. I shall give these.
God: Whether these will serve, soft pleasing touch, ever changing, good sense/smell, healthful and still looking more beautiful?
Angel B: no these can not?
God: Then, why I should take these? Lot of nature had been destroyed in making these and still with no real benefit. Lot of fallen flowers are available here, my wife can use those having all those real things as I mentioned above i.e.soft pleasing touch, ever changing, good sense/smell, healthful and still looking more beautiful.
Angel B: Awnserless.
Then Angel C competent in farming asked: O Lord, you shall definitely need grains, vegetables etc. to run your home. I shall clear lot of land for you suitable for farming.
God: whether such crops will be better healthful, no efforts in getting these and making food, and if enjoyable like fruits/milk?
Angel C : No Lord but you will get more & continuous means for foods. She can cook.
God: Why I should take it? You will kill lot of plants and devoid inhabitants of those plants from their home in clearing land and without additional real benefits. Lot of fruits and sufficient milk is available here which is sufficient for my family survival. That food is more healthful, enjoying and no energy and killings are needed to get and prepare those for food. I can conserve such energy and use for other better purpose.
Angel C; also awnserless
So on.......
