Im not Indian but im guessing the reasons are the same in Pakistan, the youth are becoming very westernised, to the point where now even in their own country's they are speaking the language of the west to one another. They probably look upon Maulanas as being backward villager types so they can't connect with them. It may help to get a few well english spoken ulemah to deliever lectures specifically directed at the youth in a manner that is effective. I think there is a darululoom in Pakistan Jamia al raheem i think, they have english as part of their syllabus. Here in the west the gap has decreased due to the younger maulanas who talk to the youth in a language they understand and give them examples from real life. the youth can relate to them more wallahu alam
