Four mental engagements
The nine ways of resting the mind, or stages of shamatha practice can be condensed into four mental engagements (Wyl. yid la byed pa bzhi):
- Tightly Focused Engagement – relates to the first two stages of resting the mind
- Interrupted Engagement – this occurs from stage three to stage seven, when one is still susceptible to the obstacles of dullness and agitation and is therefore unable to abide for a long time
- Uninterrupted Engagement – at stage eight one is able to remain unaffected by the obstacles of dullness and agitation without too much exertion
- Effortless Engagement – at the ninth stage one is able to maintain the practice effortlessly
