After developing the former path from becoming familiar with it, meditate on the four means of true abandoning:
On the middle level of the path of accumulation
We truly abandon the four attachments to good and evil.
By yearning, effort, diligence, and exertion.
So that non-arising of non-virtue will be produced, yearning and effort are produced. We strive diligently and exert ourselves to abandon persons and so forth that produce the non-arising of virtue. In order that its arising may increase, we produce effort and so forth, those four. The Middle Length Prajñaparamita says:
Subhuti, what are these four true ways of abandoning? They are like this. In order that non-arising of the non-virtuous may be produced, we produce yearning. We make an effort. We are diligent. We try to exert ourselves supremely.
