Divisions within Hinduism?
In Hinduism there is no real divisions, or everybody is part of a division from everybody else. The experts apply labels onto people to be able to categorize beliefs easier.
In Vaishnavism Hindus worship Vishnu as the supreme God. In Shaivism the worship Shiva. In Shaktism they worship Shakti. And in Smartism they believe that multiple deities make up the whole God.
