Which 5 Mental Abilities give Final Knowledge?
The Blessed Buddha once said:
Bhikkhus, there are these 5 mental abilities
(indriya). What five?
The ability of
Faith
(saddhā)
The ability of
Energy
(viriya)
The ability of
Awareness
(sati)
The ability of
Concentration
(samādhi)
The ability of
Understanding
(pañña)
These are the five abilities.
When a Bhikkhu has understood
as they really are the gratification,
the danger, and the escape in the case of these five abilities, then
this Bhikkhu is released by
non-clinging, then he is called an Arahat,
one whose mental fermentations are eliminated, who has completed
the Noble life, who has done what should be done, put down the
burden,
reached his own goal, utterly broken the chains of ever new
re-becoming,
one who is completely liberated through final knowledge...
