10. Patisankha-nana (Knowledge of Reflective Contemplation)
In the previous yanas, fear, danger, and disgust led to a desire for deliverance from nama and rupa (9th yana). In this yana, motivated by this desire to be free of rupa and nama, the yogi tries to find a way to escape – but does not yet know how. Having just realized the three characteristics in rupa and nama the feeling is strong to escape from them
The cause of the desire to escape is from the 7th, 8th and the 9th yana, which have come together to produce a very clear and strong panna and desire to get rid of kilesa, and to try to find a way for deliverance: a way to get to the end of samsara-vata, which seems to stretch out for a long way into the future. In this yana, the yogi sees the three characteristics more often than in the previous ones. Having seen that rupa and nama are impermanent, suffering and without self, there is a strong desire to end this suffering.
(The Buddha said that only the Three Characteristics can lead one out of suffering. A yogi who has never seen the Three Characteristics cannot escape from samsara-vata. There is only one way that leads to nibbana, and that is to see nama and rupa as anicca, dukkha and anatta
