You can reach the monks guide from the shop (s,e,all n,climb cliff (you need a cetain amount of str) then head south)
There is a small quest to join the monks (clue check out the bell tower), also the parts you need for the (clue) broom are just at the bottom of the cliff and around that area e.g only 1 or 2 rooms away from cliff bottom. also you might need a cloth to do some polishing (check bottom of the cliff ;-) )
The 2nd thing you require is approval (be aware that most of the elder monks don't play anymore so try to ask in chat.
Futher details to come.
