If one is reading Holy Bible or Koran, one needs to adhere that they are the only god.

But in nowhere in Hinduism, Buddhism, Jainism, Sikhism, ... Or any other religions from Indian origin claim their's is the only truth.

All of them are completely fine with different view points.

For example Hinduism is too broad, it literally accepts everything.

For Ex: There is only one God, there are many gods, there is no God. One can be an atheist and be a good Hindu. You need to pray to god, you shouldn't pray to god.

But there is an unification among all Indian religions. For ex: All religions go in search of God/Truth.

Any how, Bhagavadgita, should rather be looked up-on like a more of philosophical text rather than religious book. It is the essence of MahaBharata, yet another religious text book.
