Religion is found only in human species in creation as animals cannot embrace a religion. There is an unanswered question "Whether God created human? Or Human created God?" This question arises from the 'limited mind' which cannot reach certain domain beyond the concept of 'Creator & Created'.
Religion is standing on a flimsy foundation called "Belief" which is created by repeated conditioning. If I am taken to a temple when I was a small child and was told the deity is the God several time, it creates a belief system combined with several rituals leads to a religion. In summary 'Religion is just a belief'.
When the religion is just a bundle of 'Rituals' & 'Superstition' then it has no social value. That is the reason our Masters have created 'Epics' which are stories like Ramayana & Mahabharata through which certain values of peaceful living is subconsciously programmed.
When we hear Rama obeyed his father to relinquish his kingdom, we are programmed to respect parents. When the moral values are instilled in the mind the people social network becomes peaceful and aligned.
There are many aspects of religion taught by priest are not found in the scriptures!! What is scripture? It is the holy document supposed to have documented the sayings of the Prophet. In variably the prophet never authored the Holy book in his life time; but their disciples who heard his teachings have recorded it in the holy document.
Among few religions which does not have a prophet, Hinduism is one among them. Then what is the holy book of Hinduism? They are hundreds of them where experiences of the 'Seer' is recorded. They are called Upanishads. 'Upa' means 'Master'. 'Shad' means sitting below the master. These were taught by Masters to their disciples. Hence 'Upanishads'.
