India, Afghanistan supporting Militants

Thats fine...but so far no one has given me a proper answer.

Why would India be interested in de-stabilizing Pakistan? What does India gain with Pakistan in chaos?

Why would the Pakistani Taliban be taking their marching orders from Hindu India?

Why would the Taliban be taking their orders from India and yet the Pakistani Taliban attacking Pakistan while their Afghan Taliban attacking US, NATO and Indian Embassies?

Is there any proof of Indian involvement in these activities?

From what I know there is none, and Pakistanis just use India to hide behind instead of confronting their own failures.
