I was wondering whether the qualities (particularly calm) that come with a concentrated mind, are often confused with feeling numb, or repressed? Or is this just a result of penetrating deeper into one's experience - the peripherals and texture of sensations get blotted out, and you are left with a core? (if that makes sense).
For instance, when breathing, I find the more concentrated I am - the more I am aware of the presence of breath, or absence - but I do not focus so much on the feeling of it, ie, its texture, feeling, temperature etc. is this standard in concentration practise?
I guess this is similar to the argument that having a more reactive mind, can make you feel 'more alive'. I know artists who think work on ideas like these. But I am wondering whether I am actually practising concentration, or simply repressing or numbing other sensations and occurrences in the mind..
