A Banyan (FRMP) practises one craft in several posts at once, all in one world, and keeps lifting the standard of that craft whether or not any post asks for a higher standard.
A Banyan’s world, their work environment, stays the same, with the same standards in every post. Every job or seat a Banyan holds counts as a post, paid or unpaid, and the craft behind the posts can be medicine, law or engineering as well as woodwork or pastry. Over the years the set of posts changes. A Banyan adds a post, hands a second post to a successor or moves to a senior grade in a third post.
An architect runs her own practice in one city, teaches the course that prepares the city’s young architects for their professional exam and sits on the panel that reviews the city’s largest building plans. Practice, course and panel are paid from three different purses, yet all three are architecture, and all three are about the buildings of one city.
For a Banyan, holding several posts is part of how the craft gets better, because each post brings problems the other posts do not meet. For the architect, the review panel shows what the city’s other firms get wrong, the practice keeps the architect’s judgement on the panel tied to real buildings, and the course passes both lessons on to the city’s next architects. However, the push for mastery runs in every post at once, so the hours for any one post are fewer than that post could use.
