Hinduism is sometimes considered to be a polytheistic religion, but such a view tends to oversimplify a diverse system of thought with beliefs spanning monotheism, polytheism, panentheism, monism and even atheism. For instance, the Advaita Vedanta school holds that there is only one causal entity (Brahman), which manifests itself to humans in multiple forms while many scholars consider Samkhya to have atheistic leanings.
