Passage:
Philosophyin the East is an art of life and way of living. The proper aim of philosophising, according to the Indian mind, is not to obtain knowledge for its own sake but for the sake of making life better. Philosophise in the soil of India is a personal attitude towards life and the universe. To philosophise is not merely to read and know philosophy; it is also to think philosophically. Philosophy begins in wonder, doubt and curiosity. It grows out of our developing awarness of the problems of human existence. Philosophy does not shrink from facing the difficult and unsolved problems of our life. There are certain perennial problems which interest mankind and for which philosophers have sought answers. Philosophy is primarily conceened with the soul, God, immortality, world, knowledge and similar other problems, which again owe their solutions to the proper estimate of life. Many questions, however, have been answered only tentatively, and many problems remain unsolved.
