Dear Robert,

Thank you for translation. According to this passage the way of
sukkhavipassaka is quite difficult.

Are there any certain examples of sukkhavipassaka in the Tipitaka?

r> However not all beings have the accumulations to
r> master the jhanas (I mean genuine jhana, not imitation).

Certainly not all - peta can't do it.
Yet in my opinion any person who is able to fall in love deeply, is able as
well to develop more skillful jhana.

"Lakkhana jhana" is a part and parcel of overall Buddhist jhana practice.
