Then there are some minor things which I would also like to say. It is important for you to know that all of your thoughts come from the outside. None of them come from within, they all come from the outside. There may be some inner basis for the thought inside you, but remember that all your thoughts come from the outside. The thoughts themselves come from the outside but there are grooves along which they run inside you.
If someone thinks abour money, the thought of money must have come from the outside but the desire for money comes from inside, its seed is inside. The thoughts come from the outside and then attach themselves to your desires. If someone is thinking of sex the desire for sex comes from outside, but there is a seed inside to which this desire attaches itself. Your thought comes from outside but there is a seed for this thought inside you. All your thoughts come from the outside.
To purify your thoughts it is important to realize that the thoughts which enter your mind don\'t come accidentally. You should be alert to the fact that the thoughts which enter you are the ones that you actually want; the rest you just throw away.
As I said earlier, if someone is throwing garbage into your house you will fight with that person, but if someone is throwing garbage into your mind you will not fight with him. If I meet you on the road and start telling you the story of a movie, you will not object. But if I come to your house and throw some garbage into your house you will ask me, \"What are you doing? This is not right.\" And if I fill your mind with garbage, if I tell you the story of a movie you will listen to it very happily.
You ar not aware that your mind can also be filled with garbage. You are each others\' enemies: you keep on dumping garbage into each others\' minds. What are the people that you consider to be your friends doing to you? -- nobody betrays you more than they do. Your enemies are better than they are; at least your enemies don\'t fill your head with rubbish because they don\'t talk to you.
You are all filling each others\' heads with garbage and you are so fast asleep that you don\'t realize what you are taking in. You take everything in. You are like a guesthouse where there are no caretakers and no guards outside to see who is coming in and who is going out. You are a place where anyone can come in man, animal, thief or cheat. And when he feels like it he can leave and if he doesn\'t feel like leaving he will stay.
Your mind should not be like a guesthouse. If your mind is like a guesthouse, if it is not well protected, then it will be difficult for you to become free of impure thoughts. You should consciously watch over your mind.
The second step towards achieving purity of thoughts is the need to watch your thoughts. There should be a certain watchfulness. You should be constantly watching what is happening inside you and rejecting whatsoever is useless.
Recently, I was traveling. There were two of us in the train compartment, another man and myself. He wanted to chat with me. As soon as I sat down in my seat he offered me a cigarette, I said, \"I am sorry, but I don\'t smoke.\"
He put the cigarette back. A little while later he took out a betel leaf and offered it to me: \"Please accept it.\"
I said, \"I am sorry, but I don\'t want it\"
Again he put it away and sat down. Then he picked up his newspaper and asked me, \"Would you like to read it?\"
I said, \"I don\'t want to read.\"
Then he said to me, \"It is so difficult -- you refuse to accept whatever I offer you.\"
I said, \"A person who simply accepts everything is a fool.
And with what you are offering me I would also try to keep away from you. I will not take it, but I also wish it were taken away from you.\"
If you have nothing to do, what do you do? You will pick up the newspaper and start reading it because you have nothing to do. It would be better to simply sit and do nothing than to collect all that junk. There is nothing wrong with doing nothing, but there are some fools who say that it is better to do anything rather than to do nothing. This is not true. It is always better to do nothing than to do something harmful, because at least in those momements you are not losing anything and you are not collecting any rubbish.
So be aware about this. If you watch the movement of thoughts inside you it is not difficult to keep your thoughts pure. And it is not difficult to recognise impure thoughts: thoughts that create a kind of restlessness inside you are impure thoughts and thoughts that create a flow of peace inside you are pure thoughts. Thoughts that bring joy to you are pure thoughts. Thoughts that bring joy to you are pure and thoughts that create any kind of disturbance are impure thoughts. You have to avoid such thoughts. And if you constantly watch your mind, your thoughts will become more and more pure.
And the third thing: there are many impure thoughts in the world that keep on repeating. These impure thoughts create a fire, and the smoke from these impure thoughts enters into your consciousness and surrounds you and smothers you. But don\'t forget that there are a few flames of pure thoughts still burning, there are still a few waves of pure thought alive. In this whole ocean of darkness there are still a few sources of light. Try to be close to these. This is what I call satsang.
Although the world is very dark it is not all darkness, there are a few lamps burning. Even if they are made of clay and even if the wick is small, at least they exist. You should try to be close to them because when you take your unlit lamp to one which is lit, there is every possibility that by being so close to a lighted lamp the unlit lamp will light up again. It is possible that it too will lose the smoke and start burning bright again.
Move closer to the flames that stand for truth, goodness and beauty. Bring yourself closer to them. Move cloer to those thoughts, to those people, into the waves of those thoughts where it becomes possible to light your lamp.
You can do this in three ways: by being close to pure and true thoughts, by being close to pure and true people, and mainly and most importantly, by being close to nature. Nature never has impure thoughts. If you look at the sky and you go on looking at it, you will find that the sky does not encourage any impure thoughts in you. Instead it will clear all the rubbish in your head and you will find that by looking at the sky you feel you have become one with it. If you look at a waterfall you will feel that you have become part of the waterfall. If you are in a forest full of greenery you will feel you have also become one of the trees.
Once a man asked a sage, \"I would like to know truth. How do I do it?\"
The sage said, \"There are too many people at the moment, come back when there is no one around.\"
He did not go to see the sage the whole day, he waited until the evening when there was no one around. It was dark, the lamps were being lit and the sage was alone. He was just about to close his door when the man said, \"Wait. Now there is no one. You have seen all the people who came to see you.I have been waiting outside for everyone to leave so that I could come in. Now I am here and I want to ask you how I can become silent and how I can get enlightened?\"
The sage replied, \"Come outside. It is not possible in this hut because the lamp which is burning has been made by man. And it is not possible inside this hut because the hut itself has been made by man. Come outside. There is a big world outside which has not been created by any man, it was created by God. Come outside where there is no sign of human creation.\"
Remember, man is the only animal that leaves impure impressions behind: no other animal does that.
They went outside. There were bamboos, it was a full moon night and the moon was right overhead. The sage stood in front of the trees...one minute, two minutes, ten minutes, fifteen minutes....until the man asked, \"Say something. You are just standing quietly. I don\'t understand.\"
The sage said, \"If you could you would have understood. Simply stand quietly I have become a bamboo and you can also become one.\"
The man said, \"This is very difficult.\"
And the sage said, \"This is my method. When I stand near these bamboos, after some time I forget that I am different and I become a bamboo. Looking at the moon, after some time I forget that I am different and I become the moon.\"
