These are some excepts from 'My Master' written by Swami Vivekananda emphasizing the unity of religions:
" This man(Sri Ramakrishna) came to live near Calcutta, the capital of India, the most important university town in our country which was sending out sceptics and materialists by the hundreds every year. Yet many of these university men sceptics and agnostics used to come and listen to him. I heard of this man, and I went to hear him. He looked just like an ordinary man, with nothing remarkable about him. He used the most simple language, and I thought "Can this man be a great teacher?" crept near to him and asked him the question which I had been asking others all my life: "Do you believe in God, Sir?" "Yes," he replied. "Can you prove it, Sir?" "Yes." "How?" "Because I see Him just as I see you here, only in a much intenser sense." That impressed me at once. For the first time I found a man who dared to say that he saw God ,that religion was a reality to be felt, to be sensed in an infinitely more intense way than we can sense the world. I began to go to that man, day after day, and I actually saw that religion could be given. One touch, one glance, can change a whole life. I have read about Buddha and Christ and Mohammed, about all those different luminaries of ancient times, how they would stand up and say, "Be thou whole", and the man became whole. I now found it to be true, and when I myself saw this man, all scepticism was brushed aside. It could be done; and my Master used to say, "Religion can be given and taken more tangibly, more really than anything else in the world." Be therefore spiritual first; have something to give and then stand before the world and give it. Religion is not talk, or doctrines, or theories; nor is it sectarianism. Religion cannot live in sects and societies. It is the relation between the soul and God; how can it be made into a society? It would then degenerate into business, and wherever there are business and business principles in religion, spirituality dies. Religion does not consist in erecting temples, or building churches, or attending public worship. It is not to be found in books, or in words, or in lectures, or in organisations. Religion consists in realisation. As a fact, we all know that nothing will satisfy us until we know the truth for ourselves. However we may argue, however much we may hear, but one thing will satisfy us, and that is our own realisation; and such an experience is possible for every one of us if we will only try. The first ideal of this attempt to realise religion is that of renunciation. As far as we can, we must give up. Darkness and light, enjoyment of the world and enjoyment of God will never go together. "Ye cannot serve God and Mammon." Let people try it if they will, and I have seen millions in every country who have tried; but after all, it comes to nothing. If one word remains true in the saying, it is, give up every thing for the sake of the Lord. This is a hard and long task, but you can begin it here and now. Bit by bit we must go towards it.
The second idea that I learnt from my Master, and which is perhaps the most vital, is the wonderful truth that the religions of the world are not contradictory or antagonistic. They are but various phases of one eternal religion. That one eternal religion is applied to different planes of existence, is applied to the opinions of various minds and various races. There never was my religion or yours, my national religion or your national religion; there never existed many religions, there is only the one. One infinite religion existed all through eternity and will ever exist, and this religion is expressing itself in various countries in various ways. Therefore we must respect all religions and we must try to accept them all as far as we can. Religions manifest themselves not only according to race and geographical position, but according to individual powers. In one man religion is manifesting itself as intense activity, as work. In another it is manifesting itself as intense devotion, in yet another, as mysticism, in others as philosophy, and so forth. It is wrong when we say to others, "Your methods are not right." Perhaps a man, whose nature is that of love, thinks that the man who does good to others is not on the right road to religion, because it is not his own way, and is therefore wrong. If the philosopher thinks, "Oh, the poor ignorant people, what do they know about a God of Love, and loving Him? They do not know what they mean," he is wrong, because they may be right and he also.
To learn this central secret that the truth may be one and yet many at the same time, that we may have different visions of the same truth from different standpoints, is exactly what must be done. Then, instead of antagonism to anyone, we shall have infinite sympathy with all. Knowing that as long as there are different natures born in this world, the same religious truth will require different adaptations, we shall understand that we are bound to have forbearance with each other. Just as nature is unity in variety an infinite variation in the phenomenal as in and through all these variations of the phenomenal runs the Infinite, the Unchangeable, the Absolute Unity, so it is with every man; the microcosm is but a miniature repetition of the macrocosm; in spite of all these variations, in and through them all runs this eternal harmony, and we have to recognise this. This idea, above all other ideas, I find to be the crying necessity of the day. Coming from a country which is a hotbed of religious sects and to which, through its good fortune or ill fortune, everyone who has a religious idea wants to send an advance-guard I have been acquainted from my childhood with the various sects of the world. Even the Mormons come to preach in India. Welcome them all! That is the soil on which to preach religion. There it takes root more than in any other country. If you come and teach politics to the Hindus, they do not understand; but if you come to preach religion, however curious it may be, you will have hundreds and thousands of followers in no time, and you have every chance of becoming a living God in your lifetime. I am glad it is so, it is the one thing we want in India.
We have to recognise that each one of them has the same saving power as the other. What you have heard about their difference, whether in the temple or in the church, is a mass of superstition. The same God answers all; and it is not you, or I, or any body of men that is responsible for the safety and salvation of the least little bit of the soul; the same Almighty God is responsible for all. I do not understand how people declare themselves to be believers in God, and at the same time think that God has handed over to a little body of men all truth, and that they are the guardians of the rest of humanity. How can you call that religion? Religion is realisation; but mere talk mere trying to believe, mere groping in darkness, mere parroting the words of ancestors and thinking it is religion, mere making a political something out of the truths of religion is not religion at all. In every sect even among the Mohammedans whom we always regard as the most exclusive even among them we find that wherever there was a man trying to realise religion, from his lips have come the fiery words: "Thou art the Lord of all, Thou art in the heart of all, Thou art the guide of all, Thou art the Teacher of all, and Thou caress infinitely more for the land of Thy children than we can ever do." Do not try to disturb the faith of any man. If you can, give him something better; if you can, get hold of a man where he stands and give him a push upwards; do so, but do not destroy what he has. The only true teacher is he who can convert himself, as it were, into a thousand persons at a moment's notice. The only true teacher is he who can immediately come down to the level of the student, and transfer his soul to the student's soul and see through the student's eyes and hear through his ears and understand through his mind. Such a teacher can really teach and none else. All these negative, breaking-down, destructive teachers that are in the world can never do any good.
This is the message of Shri Ramakrishna to the modern world: "Do not care for doctrines, do not care for dogmas, or sects, or churches, or temples; they count for little compared with the essence of existence in each man which is spirituality; and the more this is developed in a man, the more powerful is he for good. Earn that first, acquire that, and criticise no one, for all doctrines and creeds have some good in them. Show by your lives that religion does not mean words, or names, or sects, but that it means spiritual realisation. Only those can understand who have felt. Only those who have attained to spirituality can communicate it to others, can be great teachers of mankind. They alone are the powers of light."
The time has come for renunciation, for realisation, and then you will see the harmony in all the religions of the world. You will know that there is no need of any quarrel. And then only will you be ready to help humanity. To proclaim and make clear the fundamental unity underlying all religions was the mission of my Master. Other teachers have taught special religions which bear their names, but this great teacher of the nineteenth century made no claim for himself. He left every religion undisturbed because he had realised that in reality they are all part and parcel of the one eternal religion. "
