please let me know if i'm correct or completely wrong..

what makes up the hindu religion is vaishnavism and shaivism.

The six traditional schools of Hindu philosophy (Samkhya, Yoga, Nyaya, Vaisheshika, Purva Mimamsa, Vedanta) define Astika [6] (believer, Hindu) as one who accepts the authority of the Vedas as supreme.

You are correct that Vaishnavism and Shaivism are two major sects within the Hindu religion. However, Hinduism is a complex and diverse religion with a wide range of beliefs, practices, and traditions. It is not solely defined by these two sects.
