“Experiencing bliss, I shall breathe out,” thus he trains himself;
“Experiencing bliss, I shall breathe in,” thus he trains himself.”
Buddha, Anapanasati Sutta
Explanation of Anapanasati Stage Six by Buddhadasa Bhikkhu
The explanation of this Stage follows in all respects the pattern of the explanation of the preceding Stage — almost word for word. The only difference is that in this Stage the meditator, instead of rapture, contemplates bliss which is akin to rapture. But since bliss and rapture are both feelings, we can treat them collectively as one. Therefore the explanation of contemplation of bliss is in every way the same as that of contemplation of rapture. The only thing to be taken
into consideration is the differences in the specifically individual characteristics of rapture and bliss.
