"Everything animate or inanimate that is within the universe is controlled and owned by the Lord. One should therefore accept only those things necessary for himself, which are set aside as his quota, and one should not accept other things, knowing well to whom they belong." (Isopanisad 1)
"This realization is wanting. Krsna claims proprietorship over all forms -- including American forms, African forms, cat forms, dog forms, tree forms, etc. -- for in actuality He is the proprietor and the supreme father. If we simply realize this, we attain God realization. Actually, if we realize God as prescribed in the authorized books and Vedic literatures, we will find that there will no longer be quarrels between this party and that party. Everything will be peaceful.
"Everyone has the right to use God’s property, just as a son has the right to live at the cost of his father. It is stated in the scriptures that even a small animal in the home must be given some food. That is spiritual communism. No one should remain hungry, not even a serpent. We are always afraid of serpents, but if we find a serpent to be living in our house, it is our duty to see that the serpent is also fed. This is the conception of God consciousness, or Krsna consciousness: samah sarvesu bhutesu. One who is transcendentally situated is equally disposed to every living entity. Thus the Bhagavad-gita points out that when one sees everyone equally, as part and parcel of the Supreme Lord, one actually begins his devotional life. This Krsna consciousness movement is trying in an authoritative way to make everyone understand what he is and what the aim of life is. This process of purification of the heart is very easily accomplished. One simply has to chant this maha-mantra -- Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. It can actually be seen that in this movement there are boys and girls from different countries and different religions, but no one is concerned with any particular section, country, or religious body. We are simply concerned about knowing ourselves and our relationship with God."
