二、辨息相中有四：一、風；二、喘；三、氣；四、息。分別四種之相，具如調息中說。但數風則散，數喘則結，數氣則勞，數息則定。行者應當捨三存息，善取不聲不結，綿綿若存若亡之相而用之。

Second, in distinguishing the marks of breath, there are four: 1. wind; 2. panting; 3. vapor; 4. breath. The differentiation of these four marks is fully as explained in [the section on] regulating the breath. However, counting wind causes scattering; counting panting causes knotting; counting vapor causes fatigue; counting breath leads to absorption. The practitioner should abandon the three and retain the breath, skillfully adopting the mark that is without sound, unknotted, continuous, and as if present yet as if absent, and use that.
