Does an Arahant accumulate kamma in his/her life? Cetana (Intention) is a universal mental factor which can be seen in every consciousness even in Arahants'.
Kamma is the intention in one's consciousness.


I have thought about the below statements based on the above mentioned two factors. But couldn't come to a conclusion. My questions are,


"An Arahant accumulates kamma in his/her life and has kammic fruit for that kamma in the same life." Is this statement true?
"An Arahant accumulates kamma in his/her life but has no kammic fruit for that kamma." Is this statement true?
"Intention (The mental factor, Cetana) is not kamma in Arahants' consciousness" Is this statement true?
Cittas are classified in various ways. One such classification is according to their nature. In this classification we have:


Cittas which are resultant states of consciousness, vipaaka, the effects of previous kamma.
Cittas which are causes for action (kamma) through body, speech, or mind. We may call these "causative cittas." A wholesome citta (kusala citta) will issue in wholesome action and an unwholesome one (akusala citta) in unwholesome action.
Cittas which are neither kamma nor its result. These are called kiriya cittas. They are kammically ineffective, being merely functional. Some kiriya cittas perform simple functions in the process of consciousness, others represent the actions and thoughts of arahants, who no longer generate fresh kamma. Read more here


Therefore, 


Statement 1: False
Statement 2: False
Statement 3: True, but they are called kiriya cittas. The term is indicative of the functional nature which is different from the intention of a worldly person.
