In Mathematics, Numbers can be classified as Real and Imaginary.

•  Real includes
  • rational
  • irrational
• Imaginary is neither rational nor irrational... It is the square root of  a negative number.

In our society, Faiths/Religions can be classified in the same manner.

• Some religions possess Rational Thinking. These are closer to Science or Reality.
• Some possess Irrational Thinking. These usually  carry some fantasy but are closer to Science.
• And other possess Imaginary Thinking. They are tough nut to crack. But the concept is not wrong. It can be undertood only by an Intellect.
