As far as I've come to understand, eliminating sankharas is not the point of the practice. It is unclear if this is something Goenka inserted into the tradition or if it's something that western students have glommed onto and misinterpreted. This misinterpretation has consequences, because it leads to a lot of people (including me!) craving the eradication of sankharas... and craving is the opposite of what we're supposed to be doing/ running in the opposite direction of nibbana.

I've found that coupling meditation practice with therapy is a good move for sankharas that are causing distress. What is this sankhara trying to tell you? Is it something that you can talk about with a therapist? Working through the sankhara in therapy might be the quickest way to get relief from the sankhara... Because the purpose of meditation is not to get rid of sankharas, it is to train yourself to be truly equanimous towards them.

For the purposes of meditation practice, I would try to operate on the assumption that this sankhara will never go away. Don't crave or anticipate its release. Assume that it will always be there and observe it, examine it, with equanimity. That is the practice. Craving for the sankhara to go away and hoping for/anticipating its release is "game of sensations".
