Realize your true nature. That is all there is to do. Know yourself as you are - infinite Spirit. That is practical religion. Everything else is impractical, for everything else will perish.
You and I and everything in the universe are that Absolute, not parts, but the whole. You are the whole of that Absolute, and so are all others, because the idea of part cannot come into it.
But on the heights of the Himalayas I have a place where I am determined nothing shall enter except pure truth. There I want to work out this idea about which I have spoken to you today. There are an Englishman and an Englishwoman in charge of the place. The purpose is to train seekers of truth and to bring up children without fear and without superstition. They shall not hear about Christs and Buddhas and Shivas and Vishnus - none of these.
How long do you remember that it is the Lord who is making you work? But then, by repeatedly analysing like that, you will come to a state when the ego will vanish and in its place the Lord will come in. Then you will be able to say with justice "Thou, Lord, art guarding all my actions from within." But, my friend, if the ego occupies all the space within your heart, where forsooth will there be room enough for the Lord to come in? The Lord is verily absent!
Who will bring light to the poor? Who will travel from door to door bringing education to them? Let these people be your God-think of them, work for them, pray for them incessantly. The Lord will show you the way.
Do not be afraid of a small beginning. great things come afterwards. Be courageous. Do not try to lead your brethren, but serve them. The brutal mania for leading has sunk many a great ships in the waters of life. Take care especially of that, i.e. be unselfish even unto death, and work.
I must remark that what I mean by our religion working upon the nations outside of India comprises only the principles, the background, the foundation upon which that religion is built.
True religion is not talk, or doctrines, or theories, nor is it sectarianism. It is the relation between soul and God. 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 organizations. Religion consists in realization. We must realize God, feel God, see God, talk to God. That is religion.
Do not believe a thing because you have read about it in a book. Do not believe a thing because another man has said it was true. Do not believe in words because they are hallowed by tradition. Find out the truth for yourself. Reason it out. That is realization.
Modern Hinduism, modern Jainism, and Buddhism branched off at the same time. For some period, each seemed to have wanted to outdo the others in grotesqueness and humbuggism.
