Most of us have a different perpective on life, some of us are happy about life and most of them are not. It's based on many factors around us including us. Finding a right Muudy for the Jaady is the trick. Most of us fails in doing this and this is where fate plays it's role in a very strong way and we have no influence on that.
If we select the wrong muudy, we end up screwing our life. Our karma decides this and to escape from this is to remain bachelor forever. Instead of eating chilly, we can stay hungry.
