Memory is a mental faculty, a distinct aspect of the mind. It is a recording mechanism which records all that falls upon it through any of the five senses. What one sees, hears, smells, touches and tastes is recorded upon the memory. A form, a picture, an image, once seen, sometimes remains in the memory for the whole of one's life if it is well recorded. In the life of the world one hears so many words during the day - yet some words which the memory has recorded remain for one's whole life, as living as ever.
