Is it talking about a human dwelling in jhana, or a brahma realm being in rupa vacara doing jhana?
And why would a human or Brahma in jhana, supposedly percipient of 'rupa', be doing four jhanas which abhidhamma is saying is an arupa attainment "bhāveti ajjhattaṃ arūpasaññī " (meditator not percipient of internal rupa)

Method 2: The Stations of Mastery (abhibhayatanani).
1. “Forms as Limited”
(a and b) Fourfold and Fivefold Jhāna.
Which are the states that are good?
When, that he may attain to the heavens of Form, he
cultivates the way thereto, and, unconscious of any part of his corporeal self, but seeing external objects to be limited, gets the mastery over them with the thought “I know, I see!” and so, aloof from sensuous appetites, aloof from evil ideas, enters into and abides in the First Jhāna, etc… . then the contact, etc., that arises—these … are states that are good.
Repeat in the case of the 2nd to the 4ih Jhāna on the Fourfold System, and of the 2nd to the 5th Jhāna on the Fivefold System.
