4.（第四禅）如是证得了第三禅时，同于上述的对于五种行相业已习行自在，从熟练的第三禅出定，觉得此定依然是近于敌对的喜，因此三禅中仍有乐为心受用，故称那（乐）为粗，因为乐粗，故支亦弱，见此三禅的过失已，于第四禅寂静作意，放弃了对第三禅的希求，为了证得第四禅，当修瑜伽行。

Ñ(IV,180): Once 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 third jhāna, he can regard the flaws in it thus: 'This attainment is threatened by the nearness of happiness; "Whatever there is in it of mental concern about bliss proclaims its grossness" (D.i,37; see Ch. IX, n. 20), and its factors are weakened by the grossness of the bliss so expressed'. He can bring the fourth jhāna to mind as quieter and so end his attachment to the third jhāna and set about' doing what is needed for attaining the fourth.
