Dear Majed Ali, the so-called holy books are creations of sur-realistic visionaries. They are no more serious than Gulliver's Travels or Aesop's Fables.
Life on planet earth is the only thing known to mankind. Enjoy that to the fullest extent possible without harming others for getting rewards in an imaginary life here-after.
Believe in yourself. Beleive in the basic goodness of all humanbeings. Beleive in the principles of neo-humanism and modern civil laws.
