What is there to understand? The significance of life? How long will it take to understand the significance and the meaning of life? 20 years? 30 years? And the same question will be here in another 20 years, I guarantee you. Until you stop asking that question. When that question is not there, you are there. So that's the reason why you keep asking the question: you do not want the question to come to an end. When that comes to an end, there will not be anybody, left there, to find out the meaning, the purpose and the significance of life.
