Yes, certain problems can be solved through thinking – only those problems which are created by thinking can be solved by it. But no real problem can be solved by it, no lived problem can be solved by it. It is not created by it; it is there in life itself. Thinking will not be of much help. Only in one way can thinking help you, and that is that through thinking and thinking and thinking, you will stumble upon the truth that thinking is futile. And the moment you realize that thinking is futile for existential problems, it has helped you in a way. It is through thinking that you have come to this realization.
But problems which are created by thinking can be solved by thinking itself. For example, a mathematical problem: it can be solved by thinking, because the whole mathematics is created by thinking. For example, if there is no man on earth, will there be mathematics? There will be no mathematics. With the disappearance of human mind, mathematics will disappear. There is no mathematics in life and existence. In the garden, trees are there, but when you count one, two, three, three trees are not there, because the three is a mental thing. The trees are there, but the figures are not there. The figure three is in your mind. If you are not there, the trees will be there, but not three trees, only trees. The three is a quality given by the mind, it is a projected quality.
Mind creates mathematics, so any problem of mathematics will be solved by mind, it will be solved by thinking. Remember, you cannot solve a mathematical problem through non-thinking. No meditation will be of help, because meditation will dissolve the mind, and with the mind the whole mathematics will dissolve. So there are problems which are created by the mind; they can be solved. But there are problems which are not created by the mind, but are existential. Those problems cannot be solved by the mind. You will have to move deep in existence itself.
For example, love. It is an existential problem. You cannot solve it by thinking; rather, you will get more puzzled. The more you think, the less you will be in touch with the source of the problem. Meditation will be of help. It will give you insight, it will lead you to the unconscious roots of the problem. If you think about it, you will remain on the surface.
So remember, life problems cannot be solved by thinking. On the contrary, really, because of too much thinking you are missing all solutions, and more problems are created. For example, death. Death is not a problem created by thinking; you cannot solve it by thinking. Whatsoever you think, how can you solve it? You can console, and you can think that consolation is a solution – it is not. You can deceive yourself; that’s possible through thinking. You can create explanations, and through explanations you can think that you have solved it. You can escape the problem through thinking, but you cannot solve it. And see the distinction clearly.
