The answer

Dear Mukesh,
It seems like your friend is in a very different place in his life. It seems almost like he wass reborn. It is pssible that he has learn to shed the pleasures of our world, but he is still suffering from withdrawl from them. Just let him finish this path alone, but be there to watch him so that you may step in to help, if he needs it. This is a good thing that he is going through, so don't be worried. He is being reborn, a new man.
