When the cloud comes, you cannot see the sun. Similarly, the cloudlike substance is māyā. When māyā covers your eyes, you cannot see God, you cannot know God. But as the cloud comes and goes—it is not a permanent feature in the sky—similarly, māyā may come and go also. The process to be known: how to drive away māyā.
So how to drive away māyā, that is also . . . there are so many processes, how to become cleansed. "Drive away māyā" means something phantasmagoria is covering my eyes; I have to cleanse. That is called ceto-darpaṇa. The māyā is also in the heart. How it is? The same thing: I am servant, but I am thinking I am master. This is māyā. I am actually serving, but acting just like a businessman. He is serving; he is always busy. He is serving his customer, he is serving his clerks, his managers, his secretaries, so many. Unless he satisfies everyone, his business cannot go on. So actually he is serving.
If you go to see a big businessman's home, "My dear sir, I have no time to see you." Why? "Because I am serving." He is thinking that "I am master," but he is busy in service, so that he has no time to see anybody. If he is master, why does he say that he has no time? He must have immense time, but he has no time, because he is actually engaged in service. So this is ceto-darpaṇa-mārjanam. When you cleanse your heart, you will understand that "I am thinking that I am master, but actually I am serving." This is cleansing of the heart.
Then the next question will be, "Then whom I am serving? For what interest?" If you think that "I am serving for my sense gratification: I have to eat, I have to sleep, I must have sex and I must defend . . ." These are the necessities of the body. These necessities are there in the animal form of life also. The animal also, they eat, they sleep, they have sex desire, they fulfill it, and they also defend in their own way. So these four principles are common, they fulfill it and they also defend in their own way. So these four principles are common to the human being and to the animals.
