Spirituality for the unity of mankind is the subject of a very interesting article by Dr. R. K. Kaw in the quarterly journal Indian(Bhaaratwarsh) Philosophy and culture. The writer says that each human individual is to be regarded as a part of the great divinity or a spark of the divine viz humane recognition of human, dignity in each and every individual. In our cultural heritage, the spiritual equality of man is the corner stone. This is the notion of spirituality in India(Bhaartwarsh) today as it was ever since, and it is rooted in its scriptures and philosophy. India(Bhaaratwarsh) has regarded the entire humanity as comprising a single family. From time to time saints and seers of this country have preached and practiced what is best and noblest for human being, as is clear from following evidence:

The Vedic seers have repeatedly taught(prayed for) the unity and unanimity of hearts, tranquility and peace of mankind.

The earliest Upanishads have emphasized the principle of unity and equality of mankind and the need of recognizing that principle for the (peaceful existence and welfare of the) whole human race.

Ishopnishad 6 & 7 says:

“He who see all creature in himself, himself in all creatures does not show abhorrence to any one’s own self, seeing the unity of mankind, how can there be delusion, suffering or sorrow”

World forum writes editorially:-

We should also possess a religious universalism common to all men if humanity is ever to be spiritually unified. Such a project has always been dismissed as impractical. Yet see how easily the materialists have established their scientific atheistic universalism in the present century? Sages and Seers way provides an alternative to this demoralizing utilitarianism which is destroying character of modern young people. But to universalize the way of sages and seers in the face of the dense materialism of the present age will demand more than an outpouring of arguments however reasonable and just; and will require a God like wisdom and patience in its campaigners. The magnitudes of such an aim is almost over whelming to contemplate, for the devil of utilitarianism than most people realize and can twist the most heavenly teachings to serve materialistic propaganda. This is never more evident than the way sages and seers originally good practice (when performed by man of good will).

Here we mean to say only Sanatan Dharm talk about Universal brotherhood neither Christianity nor Islam support the concept of Universal brotherhood.

proofs from Quran :

Al-TAWBAH 9:5

“So when the sacred months have passed away, then slay the idolaters wherever you find them, and take them captives and besiege them and lie in wait for them in every ambush, then if they repent and keep up prayer and pay the poor-rate, leave their way free to them; surely Allah is Forgiving, Merciful.”

Quran says : “Wherever you find a kaafir *(other than Muslims like Jews, Christians, Hindus),You kill him, You wait for him in every stead before”)

*Kaafir means an “Unbeliever” in Islam.

proofs from Bible :

Jude 1:2

And have mercy on those who doubt;

Galatians 5:19-21

Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.

Deuteronomy 17:3-5
If there be found among you, within any of thy gates which the LORD thy God giveth thee, man or woman, that hath wrought wickedness in the sight of the LORD thy God, in transgressing his covenant; And hath gone and served other gods, and worshiped them, either the sun, or moon, or any of the host of heaven, which I have not commanded; And it be told thee, and thou hast heard of it, and enquired diligently, and, behold, it be true, and the thing certain, that such abomination is wrought in Israel; Then shalt thou bring forth that man or that woman, which have committed that wicked thing, unto thy gates, even that man or that woman, and shalt stone them with stones, till they die.

Fairly clear, isn’t it? Books, claimed by many to be “holy” instructs follower to murder persons who do not believe in their god. Why haven’t we heard more about this? Because many Christians and Muslims are content to ignore certain parts of their bible and Quran while obsessing about others (i.e., cherry picking). And what of those who do not ignore such parts of their “sacred” text? We call them extremists…or worse.

There are  lots of example of hatred against non-believers but we have given only two, one from quran and three from bible..intelligent will understand in little also….
