Your realisation/insight into the nature of mind as being difficult to tame is important to vipassana insight (so dont get frustrated or worry when the mind can't be tamed - in fact it is important to notice this nature of mind).
Once, you accept this nature of mind,
- you stop controlling the mind (because controlling the mind is out of ignorance).
- and when the mind does get distracted, you are likely to have disinterest/dispassion about it or even averse to getting involved with it at all.
Important thing to do -
While you can't control the mind, YOU DO CREATE THE MIND through repeated actions and habits. Every moment you have a choice to make - if you choose the same thing again and again, it will develop a habit in the mind (and that's exactly what you have done in the past because of which mind is out of control)
eg: when problem arise, mind begins to produce associated thoughts/ideas/plans/goals/dreams according to your previous conditioning.
So, instead of trying it to tame it, you have to change the habits - you have to start acting in different ways.
Don't allow the mind to keep thinking the way it wants to. More>>
Don't allow the mind to keep following the previous patterns of thought. More>>
Don't make things more of what they are. Don't see/label "simple set of experiences" as problem/issue/conflict/obstacle or even as an entity. For example: seeing pain, greed, hatred as just what they are, and not as something wrong happening to us.
