When I was a young Platoon Commander in the military school, I would choose a starry night to teach new recruits how to 'see stars'. So on a hilltop, I would point out to them the Big Dipper and North Star, and the Southern Cross. (On most night, could only see 1 out of 2.) The North Star shows the direction of the North, and the Southern Cross, the South.
The stars can show the general direction only. Stars do not pin-point a location. On a starry night, while standing at Toa Payoh, a star could be directly over my head. If I move 10 kilometres away and stand at Yishun, that same star is still directly over my head.
And so, the 'star' could only guide the 3 wise men to the broad vicinity where Infant Jesus was. How did the wise men pin-point that particular stable where the Jesus lied in the manger.
That was where the heart took over. When their hearts were right, when they seek God sincerely and truthfully, God would lead them to the exact place.
When the heart is right, seek and you will find.
