Islam: Universal brotherhood. I do think its amazing the way Muslim Botherhood unites.
Hinduism: Its spritual and yoga teachings. (infact this religion didnt exist, the name hinduism was given by Britishers during population census to rest of indians after counting muslims and cristins)
Christianity: Being liberal and accepting change
Sikhism: Being devotional
Jainism and Buddhism: Non voilence
Mike and Rafiuddin Farooqui , my open question to you.. What do you learn from other religions? I am eagerly waiting for your reply.
