Purification of my existence, is possible. It is simply jñāna. I am . . . jñāna means knowledge. I am . . . because I am in ignorance, therefore I am thinking, "I am this body." So it requires a little jñāna, knowledge. Then we will understand that "I am not this body; I am different from this body." And because I am in ignorance, therefore I am thinking, "I am this body": "I am this white body," "I am this black body," "I am this American body," "I am this Indian body," "I am this cat's body" and "dog's body," so many different consciousness on account of this . . . basic principle is this ignorance. Ignorance.
So, that we have to cure. That is the special advantage of human life. The dogs, the cats, they cannot be cured. They cannot be given the knowledge. Because you are human being, you are together here to get this knowledge. The cats and dogs, they cannot come. They cannot take this knowledge. So we have got the advantage of getting this knowledge in this life, and again, if we go back to the cats' and dogs' knowledge, then what is the benefit of getting this body? So this civilization, this dog civilization, is so spread all over the world that it is very, very difficult to cure it. We are making little attempt, but the ignorance is so deep, the disease is so acute, it is very, very difficult. But actually the disease is there.
