"Vedanta is a system of philosophy. Reality is a logical concept. We mean by Reality or the Real, THAT which remains ever and ever. While thus permanent existence is one feature of the Reality, uniformity, changelessness, etc. are the other features.
"The quest for the Reality becomes necessary for man because he finds that the things of the world, including his body, are having only a fleeting and perishable nature. Fleetingness pre-supposes destruction or non-existence. When a thing is found to change, the change implies the destruction or disappearance of its present form and then the emergence and appearance of another form in which it is seen to exist subsequently. The fact that the things of the world are of a perishable and changing nature, we have to consider them as un-real. This unreal nature of the world and its contents naturally makes us think whether there is not anything real at all.
"The entire effort in our life is to acquire the various objects of enjoyment. Some of the objects are living, while others are inert. By the acquisition of objects we hope to preserve our peace, contentment and satisfaction. But, because the objects that we seek to acquire have a fleeting nature, we find ourselves unable to preserve them forever. Naturally, the peace, happiness and contentment we so much crave for, never reach a level of fulfilment. Therefore, it is but natural for us to wonder whether there is no possibility to find out something real, by acquiring which we can derive permanent peace and contentment."
