Instead of naming an existing religion to serve a quick purpose, I leave this job to readers to find the best fit for a religion, which should have following characteristics, which should:
1. encourage rational thinking
3. disciplined life streamlined by certain principlesReference:: Sikh Philosophy Network http://www.sikhphilosophy.net/interfaith-dialogues/645-what-would-ideal-reilgion-according-you.htmlReference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=645
4. encourage to learn more about the indescribable Supreme Power
5. encourage betterment of self and surroundings
