I wonder if she was influenced by it or if this is a rediscovery.
The fact that she associates a sensation of contraction in the forehead as thinking is very interesting.
Also the fact of there being no time or no will.
Although she goes further to conclude that she acquired will, instead of illusion of will or choice due to previously experiencing no will or choice.

Although one difference I suppose is that while Keller had no option at all of using the faculties of self-modeling enabled by language, UG Krishnamurti described it as something voluntary; clearly he could introspect if he desired to, but he could apparently relinquish this also.
Makes sense to me. A furrowed brow is a common trope of thinking hard about something, it'd make sense if the same happens on a smaller barely perceptible scale for other thoughts (supposedly this happens to our vocal chords when subvocalising in our heads). Something about focusing the senses when processing thoughts I would guess.
