Possibility of Unsuitable Technique

Upon (re)-reading this answer, I conjectured perhaps there *are* techniques unsuitable for some. It does seem to be the case with the breath for me, in my experience, despite the popularity and near universality of the breath as meditative object. In context, I'm extremely sensitive to what people call *experiential avoidance ,* and focusing on the breathing to the exclusion of all else seems to trigger this. More so, I read here that in some cases of dissociative people the breath may be difficult to focus on. My question is mainly: **Given these conditions, could *even* the breath (or any object of meditation) be truly unsuitable for some? Is it possible that other objects would be much more suitable? How would one actually *know/discover* this?** I'm particularly tempted to conclude compassion (which has a visual and affective component) might be a better alternative. Yet, I'm always brought back to the breath because I keep concluding that its a *universal* object that *should* work for everyone. **Am I wrong?** Thank you
