Now, no one can become wise. It is not an effort. One can become knowledgeable; it is an endeavor, an enterprise. You can cultivate knowledge, you cannot become wise. Wisdom is not becoming, it is being. That has to be understood.
Becoming is a time process: today you have this much knowledge, tomorrow you can have more, and the day after tomorrow more and more and more. Wisdom is not a quantity, knowledge is a quantity; so quantity can be more or less. The student has less, the professor has more. But wisdom is never less or more; it is a quality. Buddha is wise, so is Mahavira, and so is Bahaudin, and so is Zarathustra. Now you cannot say who is wiser; that is not possible. It is not a quantity, you cannot compare. They are all wise. Wisdom knows nothing of more or less.
