10.28

Next, the self samādhi destroys existence in the base of neither-conception-nor-non-conception. This heaven is the very pinnacle, which they presume to be the true self of nirvāṇa. The bodhisattva sees that this still contains subtle defilements and lacks mastery—that is, lack of mastery regarding views and thoughts, lack of mastery regarding dust-like [delusions], and lack of mastery regarding nescience; how could this be a self? In order to destroy this self, they cultivate the samādhi of the three truths to destroy it, causing them to attain non-self, the self conforming to the conventional, and the eightfold sovereign self; therefore, it is named the self samādhi.
