Q: When there is much tamas it fatigues the mind and this affects my concentration. I ought to disregard all such reactions and go forward.
If the mind gets tired, naturally it is difficult to concentrate — unless you have become separated from the mind.
Q: How to “become separated from the mind”?
You have to feel yourself even in the mental, vital, physical levels (not only above) a consciousness that is neither mind, life nor body.
– Sri Aurobindo
