Lessons from the Shampoo

A friend presented me an imported shampoo. He met me after a couple of weeks and asked me”” How was your experience with the best shampoo I gave you?”
Well at present I am on the verge of becoming totally bald. 
I replied”I should thank you for presenting me something which had no utility.I used the shampoo on my scalp and what it did to me was amazing. What little hair I had vanished and the shampoo promoted me from incomplete wisdom to complete wisdom  . I intend presenting it to you so that you also become wise externally 
The gyan I got from this incident was that we hold on to many possesions we have which  have no utility and do  not let go of them. Enjoy the bliss ness of emptiness
