In anattànupassana, one concentrates on the selfless or nosoul
nature of the ultimate nàma and råpa, and notes repeatedly
“anatta, anatta, anatta,…” for ten to thirty minutes at a stretch.
Then one takes up aniccànupassana again.
As one carries on the vipassanà meditation is this manner,
the ten insight-knowledge (vipassanà-¤àõa) will arise in due
course. Soon after the last insight-knowledge arises, magga-¤àõa
and phala-¤àõa (the Path and its Fruition) also arise.
Ten Vipassanà-¤àõas (Ten Insight Knowledge)
1 Sammasana-¤àõa
The knowledge that can investigate the three characteristic
marks of nàma and råpa in the five aggregates of
existence;
2 Udayabbaya-¤àõa
The knowledge that can investigate the arising and
passing away of the ultimate nàma and råpa in the five
aggregates of existence;
3 Bhaïga-¤àõa
The knowledge of the incessant dissolution of the
ultimate nàma and råpa;
4 Bhaya-¤àõa
The knowledge of realizing nàma-råpa and the five
aggregates of existence as fearful as they are dissolving
incessantly;
5 âdinava-¤àõa
The knowledge that realizes the fault and unsatisfactoriness
in nàma-råpa as they have been known to be
fearful;
