When I first saw your eyes beam, I thought you must have the secret 
So, I stayed to watch your magic.  
You tell me there’s no trick to it. 
You’ve shown me the strings and your mirrors. 
I hope you don’t mind,  
I’m still trying to peek up your sleeve. 
 
Happy Birthday, and thank God I do, that I met with a true teacher like you. 
With His Grace, and your guidance, I may still “turn a parasite into a prayer site.”
