I wrote to you about the subtle sounds heard by my ears. But now I hear very loud sounds in the head also. These are different not only in pitch but also in their character. They are of two types which, ring simultaneously and yet separately. The latter increases when I use will-power or draw on the Mother’s Force.
They are frequently heard when the force of sadhana is strong -I suppose they are sounds made by the vibration of subtle forces.
