Any insights about esoteric depth of concept attention

One thing I realized today in deep self-inquiry: People who are fighting with OCD, rumination, or any kind of mental health issues associated with thoughts — if anyone is engaged in fighting with thoughts and never able to rise above it, or getting frustrated by repetitive thoughts and loud mind chatter, use this idea over any methods or techniques you could possibly apply. When any thought disturbs you and makes you feel frustrated during meditation or non-meditation — just become that thought itself. Acknowledge the fact that you are that thought, and that the thought is not different from you, instead of fighting with it and creating duality. Go beyond the duality and merge with that thought to become one. When you create non-duality, you are free from thoughts — because thoughts exist only when there is duality, and the ego, with its full power, tries to separate the self from thoughts, which creates resistance. Use the same ego to acknowledge the thought, to be it itself, and gain insights from that non-duality. By doing so, you are free from controlling, observing, labeling, and resistance. I know a few of you are aware of this — but if anyone hasn't come across this idea, just cultivate it.
