1. Nobody knows when I came into being

2. You first hear about me when you are young

3. I live in a place you cannot reach

4. Nobody has ever seen me and yet we talk as if I am always there

5. I can look into the hearts of every person and tell everything about them

6. I am involved in a once-yearly event to mark my coming

7. I can be everywhere at once

8. Those who believe in me are happy



Who am I?
