He develops the enlightenment factor of discrimination of states,
- which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops the enlightenment factor of energy,
- which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops the enlightenment factor of rapture,
- which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops the enlightenment factor of tranquillity,
- which is based upon seclusion, dispassion, and cessation, maturing in release.

He develops the enlightenment factor of concentration,
- which is based upon seclusion, dispassion, and cessation, maturing in release.
