The accomplished one;
The Blessed Buddha once said: Friends, those who are accomplished in morality, masters in concentration, experts in understanding, consummated in release, fulfilled in the knowledge & vision of release, I tell you even just a short sight of those is advantageous, even just listening to them is very profitable, even just visiting them is like a golden fortune, even attending on and helping them is productive of good, even just remembering them is valuable, and going forth after or under them is therefore worthwhile, and expedient!
Why? Because, when one has heard true Dhamma from such a person, then one dwells withdrawn calmed by two kinds of seclusion: secluded in body and secluded in mind!
