Please be aware of the sixteen stages of insight:
No:6 Bhaya Nana:
The sixth stage of knowledge is bhaya nana or "knowledge of the appearance as terror."
The following characteristics can be observed:
a.At first the meditator acknowledges objects, but the acknowledgements vanish together with consciousness.
b.A feeling of fear occurs but it is unlike that generated by seeing a ghost.
c.The disappearance of nama and rupa and the consequent becoming nothingness induce fear.
d.The meditator may feel neuralgic pain similar to that caused by a nervous disease when he is walking or standing.
e.Some practitioners cry when they think of their friends or relatives.
f.Some practitioners are very much afraid of what they see even if it is only a water jug or a bed post.
g.The meditator now realizes that nama and rupa, which were previously considered to be good, are completely insubstantial.
h.There is no feeling of happiness, pleasure or enjoyment.
i.Some practitioners are aware of this feeling of fear but are not controlled by it. http://www.vipassanadhura.com/sixteen.html#fourc
