40. Pãti is zest, joy, or pleasurable interest. It is
derived from √ “pã”, to please, to delight. It is not a
kind of feeling (Vedanà) like Sukha. It is, so to say, its precursor.
Like the first two Jhàna factors, (Pãti) is also a mental
state found in both moral and immoral consciousness.
Creating an interest in the object is its characteristic. Pãti
inhibits Vyàpàda, illwill or aversion.
41. Sukha is bliss or happiness. It is a kind of pleasant
feeling. It is opposed to Uddhacca and Kukkucca (restlessness
and brooding). As Vitakka is the precursor of
Vicàra, so is Pãti the precursor of Sukha.
The enjoyment of the desired object is its characteristic.
It is like a king that enjoys a delicious dish.
Pãti creates an interest in the object, while Sukha
enables one to enjoy the object.
Like the sight of an oasis to a weary traveller, is Pãti.
Like drinking water and bathing therein, is Sukha.
This mental Sukha which should be differentiated
from Ahetuka Kàyika (physical) happiness is identical with
Somanassa. But it is a joy disconnected with material
pleasures. This pleasurable feeling is the inevitable outcome
of renouncing them (Niràmisa Sukha). Nibbànic
bliss is yet far more subtle than Jhànic bliss. There is no
feeling in experiencing the bliss of Nibbàna.
