I have realized that the past and future are real illusions, that they exist in the present, which is what there is and all there is.
Don't part with your illusions. When they are gone you may still exist, but you have ceased to live.
I see many people die because they judge that life is not worth living. I see others paradoxically gettin killed for the ideas or illusions that give them a reason for living (what is called a reason for living is also an excellent reason for dying). I therefore conclude that the meaning of life is the most urgent of questions.
