Evamadhigate pana tasmimpi vuttanayeneva pañcahākārehi ciṇṇavasinā hutvā paguṇadutiyajjhānato vuṭṭhāya ‘‘ayaṃ samāpatti āsannavitakkapaccatthikā, vicārassa oḷārikattā aṅgadubbalā’’ti ca tattha dosaṃ disvā tatiyaṃ jhānaṃ santato manasikaritvā dutiyajjhāne nikantiṃ pariyādāya tatiyādhigamāya yogo kātabbo.

（第三禅）如是证得第二禅时，已于前述的五行相中习行自在，并自熟练的第二禅出定，觉得此定依然是近于敌对的寻，因伺粗故禅支亦弱，见此第二禅的过失已，于第三禅寂静作意，取消了第二禅的希求，为证第三禅，当修瑜伽行。

Ñ(IV,200): When this has been obtained in this way, and once he has mastery in the five ways already described, then on emerging from the now familiar second jhāna he can regard the flaws in it in this way: 'This attainment is threatened by the nearness of applied thought, and its factors are weakened by the grossness of sustained thought'. He can bring the third jhāna to mind as quieter and so end his attachment to the second jhāna and set about doing what is needed for attaining the third.
