Mythology is concretized philosophy. Mythology is the science which investigates myths or fables or legends founded on remote events, especially those made in the early period of a people's existence. Mythology inspires the readers through precepts and laudable examples, and goads them to attain perfection or the highest ideal. The abstract teachings and subtle ideas are made highly interesting through the garb of stories, parables, legends, allegories and narratives. The sublime and abstract philosophical ideas and ideals of Hinduism are taken straight to the heart of the masses through impressive stories.
Mythology is slightly mixed up with a little history.
It is difficult to make a fine distinction between history and mythology. There are great truths behind the ancient mythology of Hinduism. You cannot ignore a thing simply because it has a garb of mythology. Do not argue. Keep your intellect at a reasonable distance when you study mythology.
