Your wish is never really unheard by the universe. I wished for something yesterday, not for myself, but for a friend.
I wished that the friend doesn’t find himself in a situation which might hurt him in any way. I wished that he has the power to take the right decision and if not there must be someone who could help him with it.
If you think good for people, there could be nothing in the universe which won’t let the good win over the evil. My wish is already granted.
The power of a wish should never be challenged. Wishes do come true.
