Friends:

The Seven Qualities of an Arahat:

For any fully awakened Arahat:
1: The impermanence of all constructions is perfectly seen and comprehended. 
2: The addiction and torture of all sense-desires is perfectly perceived & known..
3: His mind is only inclined towards solitude, seclusion, silent ease, and Peace...
4: The Four Foundations of Awareness are continually & perfectly established...
5: The Five Mental Abilities & Powers are thoroughly developed & consummated...
6: The Seven Links to Awakening are utterly refined and fully accomplished...
7: The Noble Eightfold Way is perfectly realized, acquired and all concluded...
By these 7 criteria, he clearly and invariably recognizes, that for him, has the
mental fermentations associated with Sense-Desire, joined with Becoming,
and grounded in Ignorance been completely and irreversibly eliminated!
Cut of at the root and like a palm tree stump never ever to grow again...
The mission is completed. Done is, what was to be done. No more of this...
