How did I get my name

Well, my background is Sri Lankan, and my religion is hindu. So that pretty much means that my names is picked based on astrology. So based on the star I was born on, my grandfather said my name had to start with a Y and it how to be worth a certain number. By that i mean we have this thing were certain letters have a value they are worth like the letter a might be worth 5. So my name had to be worth 12 and the letters in my name accumulate to 12. Plus my name apparently has something to do with a musical instrument even though I am not musical talent in any way. So there you have it thats the way I got my name some crazy hindu ways :P
