Letters of Sri Aurobindo
Volume III - Part 4
Fragment ID: 13391
The sensations you describe in the crown of the head and the upper part of the forehead are such as one often gets when the higher consciousness or Force is trying to make an open passage through the mind for itself. So it is possibly that that is happening. As for the uneasiness or feebleness there when you talk loudly etc., that also happens at such times. It is because the concentration of energy which is necessary for the inner work is broken and the energies thrown out, exhausting the parts by two inconsistent pullings. It is better when any working is going on inside to be very quiet in speech and as sparing as possible. At other times it does not so much matter.
