So nobody should claim to be the proprietor of anything, but he must accept things which are set aside by the Lord as his quota of maintenance. Now, there are many examples how we have to utilize the allotment of the Lord. That is also explained in the Bhagavad-gītā. Arjuna, he decided in the beginning that he should not fight. That was his own contemplation. Arjuna said to the Lord that it was not possible for him to enjoy the kingdom after killing his own kinsmen. And that point of view was due to his conception of the body. Because he was thinking that the body was himself and the bodily relatives, his brothers, his nephews, his father-in-law or his grandfather, they were expansion of his body, and he was thinking in that way to satisfy his bodily demands. And the whole thing was spoken by the Lord just to change the view. And he agreed to work under the direction of the Lord. And he said, kariṣye vacanaṁ tava (BG 18.73).
Therefore in this world the human being is not meant for quarreling like the cats and dogs. They must be intelligent enough to realize the importance of the human life and refuse to act like ordinary animal.
