Proposal: Instead of expending massive amounts of energy bringing an object of such high inertia to rest, why not just change the inputs you are feeding it to gradually alter its direction? Don't focus on the cessation and extinction of the turning of mind. Focus on feeding the turning of mind solvable or aesthetically pleasurable problems, to decrease the bandwidth occupied by unsolvable\fear based problems.
tldr: I'm not convinced the epicness of ego destruction is necessary for ego transmutation, if that is one's goal.
edit: Well, I just realized my analogy does not hold for all cases. In Physics, if you want to change the direction vector of an object in motion, to the opposite of its present heading, it will require at least as much energy as bringing the object to rest. So focusing on ego destruction could be worth it depending on where you want to go and where you are now.
Additionally, we also know from Physics that all motion is relative, velocity cannot be measured without a frame of reference. I think the Buddhists would argue that cessation of the turning of thought provides this otherwise missing frame of reference, enabling the thought\ego vector to accurately be measured when the turning of thought restarts.
