This could be an important factor, but the deeper question is what the vitality of the rituals depends on. As far as that is concerned, I would say that the continued success of religions depends on how convincing the meaning is that their content and therefore also the meaning of rituals have for their followers. Since these meanings are generally anchored in mythological narratives in which, for example, rituals were performed for the first time, I tend to assume that it is the persuasive power of certain stories and narratives that ensures the long-lasting success of religions and their practices. In order to be so convincing over centuries and millennia, the narratives must be written in a way that is open to interpretation, so that every new generation can still gain something from them, no matter how our societies and our environments change.

Pradeep,

There is substance in your views as the symbolism is connected to the narrative. The narratives in monotheism are notably similar. Much of Islam repeats biblical stories such as the early exile of the group to Egypt. But few of the narratives are sensible or historic. The Islamic concern with Time is interesting and the need to make both Muhammad and Jesus supernatural.
