6. Bhayatupatthana-nana (Knowledge of Fearfulness)
In this yana the wisdom is realized that nama-rupa is harmful. Because dissolution was seen in the 5th yana, the feeling arises that rupa and nama are insubstantial – always arising and vanishing quickly – and this causes fear and terror in the yogi.
The meditator sees no pleasure in rupa and nama, and even to be born in any bhava (becoming) in the future is seen as fearful – as it was in the past. This yana causes tanha to be arrested, but does not completely eradicate is. This wisdom is the enemy of tanha, but it is like putting a medication on skin that itches, and when the medication wears off, the skin begins to itch again.
