"The sages, knowing Me as the ultimate purpose of all sacrifices and austerities, the Supreme Lord of all planets and demigods and the benefactor and well-wisher of all living entities, attain peace from the pangs of material miseries."
It is further explained in Srimad-Bhagavatam that no one should claim anything as his property. Whatever property one claims to be his actually belongs to Krsna.
One should be satisfied with whatever has been allotted by the Supreme Lord and should not encroach upon the property of others. This will lead to peace in the whole world.
