Since the main 2 sects of Tantra Yoga came up w/ those and formed into Hinduism(advaita and Shaivism, obviously Vishishtadvaita was formed by the mixture of advaita and Vaishnavism)....so lets compare and contrast.

In Advaita....this is written, Jagat (the world) is not different from Brahman; however Brahman is different from Jagat" ...what does it mean?

They both agree that Universe is made up of god...however, is god more than just universe?

I know Shaivism is established in South India, where are the others located?

I wouldn't really count the difference btw. god names...b/c it is just a diff. btw names....since their true nature is unmanifested truth, it is us who gives them an identity.

Thanks.
