To identify oneself with a particular race, with a particular country or with certain ideologies yields security, satisfaction and flattering self-importance. This worship of the part, instead of the whole, cultivates antagonism, conflict and confusion.

— J. Krishnamurti, 4 June 1944.

Do not let us be clouded by words, names or labels which only bring confusion as Hindus, Buddhists, Christians and Mohammedans, or as Americans, Germans, English, Chinese. Religion is above all names, creeds, doctrines. It is the way of the realization of the supreme, and virtue is not of any country, race or of any specialized religion. We must free ourselves from names and labels, from their confusion and antagonism, and try to seek through highest morality that which is. Thus you will become truly religious and so will your State. Then only will there be peace and light in the world. If each one of us can understand that there can be unity only in right thinking, not in mere superficial, economic devices, when we become religious, transcending craving for personal immortality and power, for worldliness and sensuality, only then shall we realize the deep inward wisdom of peace and love.

— J. Krishnamurti, 28 May 1944.

I am pained by the terrorist attacks in Bombay yesterday. I pray for peace.

We may feel jealous of a successful person, but we are never jealous of the success of our own children, even though they are someone other than us. When we see ourselves in the other person, love comes naturally. And where there is love, there is no room for violence, hatred, enmity, or jealousy. Love is a substitute for everything, but there is no substitute for love. And when that love becomes divine, there is no further need to say anything!

— Swami Tejomayananda

Why is somebody glad when their own child is successful but jealous when somebody else experiences success? Isn’t it the feeling of ‘mine’ and ‘other’ that makes the difference? I am happy if ‘my’ child succeeds but jealous when some ‘other’ person is successful. If a child that is born out of you is your own, then we are all children of the same God and belong to one God. We are all born out of the same source, live in the same space, and in the end go back to the same source. Ultimately, we all dissolve into each other. Then where is the question of ‘mine’ and ‘not mine’?

Swami Vivekananda says,

If a beautiful picture belonging to another is burnt, a man does not generally become miserable; but when his own picture is burnt, how miserable he feels! Why? Both were beautiful pictures, perhaps copies of the same original; but in one case very much more misery is felt than in the other. It is because in one case he identifies himself with the picture, and not in the other. This ‘I and mine’ causes the whole misery.

— The Complete Works of Swami Vivekananda, vol. 1, p.101.

‘I’ and ‘mine’ and ‘other’ is the cause of all misery. Drop the feeling of ‘mine’ and ‘other’ and simply enjoy success, appreciate beauty wherever you find it, and you will become the embodiment of success and beauty! ‘I’ and ‘mine’ and ‘other’ is mere illusion. When you drop ‘I and mine’, the whole world becomes yours. Then what remains is the feeling of oneness, pure Love. And when there is Love, where is the room for violence, hatred, enmity, and jealousy?
