Those who have studied life and thought long enough about this subject, have arrived at the same point as the thinkers who lived as much as eight thousand years ago. Buddha has said and has realized the same things that a really wise man would realize and say today. This shows us that wisdom is the same in all ages. We may be evolving or going backward, but wisdom never changes and will always be the same. The same realization will come to all those who think deeply and try to realize what life is. In order to realize life it is not necessary for us to follow a certain religion. It is not necessary for us to be great or good, pious or spiritual. The first and most necessary thing is that we become observant. We should look at life more keenly than we do instead of living superficially. It would cost us nothing. It only takes us away from our everyday occupation for a few minutes. Life always gives an opportunity of thinking, however busy we may be.
