Religions shows the path to the immortal abode. To give solace to the weary mind in the earth-plane. To explain life's mystery to man. To show the path to immortal abode. Philosophy enumerates the whole scope of that religion, setting forth its basic principles, the goal and the means of reaching it.
Mythology is philosophy made concrete.
It consists of legends relating to the lives of great men or of supernatural beings of Avatharas and so forth. It is the abstractions of philosophy concretized in the more or less imaginary lives of men and supernatural beings. Ritual is still more concrete and is made up of forms and ceremonies, various physical attitudes, flowers and incense and many other things which appeal to the senses. This includes daily Pooja, Kalasa Pooja, Velvi Pooja, etc. Today man has become irreligious.
