Here are my views on Hindusism, and you cant talk about it without mentioning Islam or Sikihism...
Hinduism is the oldest major organized religion in this world. It is mainly practiced in India. They believe is reincarnation of the soul. Most Hindus consider cows and snakes sacred. They worship the nature and try to be at peace with it. Most Hindus also believe in Karma. Karma is a system where beneficial events are derived from past beneficial actions and harmful events from past harmful actions. A large partition of Hinduism does Yoga. Islam and Hinduism are mortal enemies. That is the reason Sikhism was created.
Sikhism is a very interesting religion. It began in sixteenth century in Northern India. The Muslims started to forcibly convert Hindus to Islam. The Hindus wanted to stop that, so they decided to pick out the most aggressive Hindus and turn them into protectors. That is how the first Singhs were created. To distinguish them they would wear turbans, orange robes, a sword and they would have long beards. It is the only religion ever created specifically against Islam.
