Just as a citadel has a gatekeeper who is astute, competent, and intelligent, who keeps strangers out and lets known people in, in the same way a noble disciple is mindful. They have utmost mindfulness and alertness, and can remember and recall what was said and done long ago. A noble disciple with mindfulness as their gatekeeper gives up the unskillful and develops the skillful, they give up the blameworthy and develop the blameless, and they keep themselves pure. This is the sixth good quality they have.

Just as a citadel has a wall that’s high and wide, covered with plaster, to defend those within and repel those outside, in the same way a noble disciple is wise. They have the wisdom of arising and passing away which is noble, penetrative, and leads to the complete ending of suffering. A noble disciple with wisdom as their wall gives up the unskillful and develops the skillful, they give up the blameworthy and develop the blameless, and they keep themselves pure. This is the seventh good quality they have. These are the seven good qualities that they possess.

And what are the four absorptions—blissful meditations in this life that belong to the higher mind—that they get when they want, without trouble or difficulty? Just as a king’s frontier citadel has much hay, wood, and water stored up for the enjoyment, relief, and comfort of those within and to repel those outside, in the same way a noble disciple, quite secluded from sensual pleasures, secluded from unskillful qualities, enters and remains in the first absorption, which has the rapture and bliss born of seclusion, while placing the mind and keeping it connected. This is for their own enjoyment, relief, and comfort, and for alighting upon extinguishment.
