Main Point

In the mahayana, everything depends on attitude, and everything is done with diplomacy.
But in vajrayanna, you cut thoughts abruptly, on the spot. You do not even take an attitude. You just do it. It is very direct and precise. Right away—bang, bang, bang, on the spot. There is no particular way to do it. Cutting thoughts is the first way of blowing up the samsaric world.

The main point that runs through every level of vajrayana practice, is that you are able to cut your mental contents directly and abruptly.
