In the book The Reality of Life, Maulana Wahiduddin Khan explains that man is born with unlimited potential, yet in the present world he finds only a very limited use for it. According to his nature, man wants to live eternally, but very soon, without his leave, death arrives and puts an end to his life. He harbours an ocean of desires in his heart but these dreams are never realized. In this case, there is no difference between a poor man and a rich man. In this book the author explains why man and the present world are so mismatched.
