"The mind lives in the no, it is a no-sayer; it's nourishment comes from saying no to each and every thing. The mind is basically atheistic, negative. There is nothing like a positive mind.
The heart is positive. Just as mind says no, the heart says yes. Of course, it is better to say yes than to say no, because one cannot really live by saying no. The more you say no, the more you become shrunken, closed. The more you say no, the less alive you are. People may think you are a great thinker, but you are shrinking and dying; slowly you are committing suicide.
If you say no to love, you are less than you were before; if you say no to beauty, you are less than you were before. And if you go on saying no to each and every thing, chunk by chunk you are disappearing. Ultimately a very empty life is left, meaningless, with no significance, with no joy, with no dance, with no dance, with no celebration.
That's what has happened to the modern mind. The modern man has said more nos than ever before. Hence the questions: what is the meaning of life? Why are we alive at all? Why go on living? We have said no to God, we have said no to the beyond, we have said no to all for which man has lived down the ages. We have proved to our hearts content that all the values man has lived for are worthless. But now we are in difficulty, in deep anguish. Life has become more and more impossible for us. We go on living only because we are cowards; otherwise we have destroyed all the reasons to live. We go on living because we cannot commit suicide. We are afraid of death, hence we go on living. We live out of fear, not out of love.
It is better to be positive, because the more positive you are the more you are moving towards the heart. The heart knows no negative language. The heart never asks "What is beauty?" It enjoys it, and in enjoying it, it knows what it is. It cannot define it, it cannot explain itself, because the experience is such that it is inexplicable, inexpressible. Language is not adequate, no symbols help. The heart knows what love is, but don't ask. The mind goes on asking but it cannot answer. The mind knows only questions and the heart knows only answers."
