9. Because the meditating (person) is compared to the immovable earth.
10. Also because the Smritis say so.
11. There is no law of place; wherever the mind is concentrated, there worship should be performed.

Practical Religion: Breathing And Meditation
Through the vistas of the past the voice of the centuries is coming down to us; the voice of the sages of the Himalayas and the recluses of the forest; the voice that came to the Semitic races; the voice that spoke through Buddha and other spiritual giants; the voice that comes from those who live in the light that accompanied man in the beginning of the earth — the light that shines wherever man goes and lives with him for ever — is coming to us even now. This voice is like the little rivulets; that come from the mountains. Now they disappear, and now they appear again in stronger flow till finally they unite in one mighty majestic flood. The messages that are coming down to us from the prophets and holy men and women of all sects and nations are joining their forces and speaking to us with the trumpet voice of the past. And the first message it brings us is: Peace be unto you and to all religions. It is not a message of antagonism, but of one united religion.
Let us study this message first. At the beginning of this century it was almost feared that religion was at an end. Under the tremendous sledge-hammer blows of scientific research, old superstitions were crumbling away like masses of porcelain. Those to whom religion meant only a bundle of creeds and meaningless ceremonials were in despair; they were at their wit’s end. Everything was slipping between their fingers. For a time it seemed inevitable that the surging tide of agnosticism and materialism would sweep all before it. There were those who did not dare utter what they thought. Many thought the case hopeless and the cause of religion lost once and for ever. But the tide has turned and to the rescue has come — what? The study of comparative religions. By the study of different religions we find that in essence they are one. When I was a boy, this scepticism reached me, and it seemed for a time as if I must give up all hope of religion. But fortunately for me I studied the Christian religion, the Mohammedan, the Buddhistic, and others, and what was my surprise to find that the same foundation principles taught by my religion were also taught by all religions. It appealed to me this way. What is the truth? I asked. Is this world true? Yes. Why? Because I see it. Are the beautiful sounds we just heard (the vocal and instrumental music) true? Yes. Because we heard them. We know that man has a body, eyes, and ears, and he has a spiritual nature which we cannot see. And with his spiritual faculties he can study these different religions and find that whether a religion is taught in the forests and jungles of India or in a Christian land, in essentials all religions are one. This only shows us that religion is a constitutional necessity of the human mind. The proof of one religion depends on the proof of all the rest. For instance, if I have six fingers, and no one else has, you may well say that is abnormal. The same reasoning may be applied to the argument that only one religion is true and all others false. One religion only, like one set of six fingers in the world, would be unnatural. We see, therefore, that if one religion is true, all others must be true. There are differences in non-essentials, but in essentials they are all one. If my five fingers are true, they prove that your five fingers are true too. Wherever man is, he must develop a belief, he must develop his religious nature.
And another fact I find in the study of the various religions of the world is that there are three different stages of ideas with regard to the soul and God. In the first place, all religions admit that, apart from the body which perishes, there is a certain part or something which does not change like the body, a part that is immutable, eternal, that never dies; but some of the later religions teach that although there is a part of us that never dies, it had a beginning. But anything that has a beginning must necessarily have an end. We — the essential part of us — never had a beginning, and will never have an end. And above us all, above this eternal nature, there is another eternal Being, without end — God. People talk about the beginning of the world, the beginning of man. The word beginning simply means the beginning of the cycle. It nowhere means the beginning of the whole Cosmos. It is impossible that creation could have a beginning. No one of you can imagine a time of beginning. That which has a beginning must have an end. “Never did I not exist, nor you, nor will any of us ever hereafter cease to be,” says the Bhagavad-Gita. Wherever the beginning of creation is mentioned, it means
