What I'm trying to figure out is some comment or motion that would mark her, to an astute observer, as (probably) Buddhist, that might come up in casual conversation on non-religious topics.
Examples of the *kind* of thing I mean: a Wiccan greeting someone with "Blessed be", a Catholic crossing him/herself...
It can't be a physical object (ie the equivalent of rosary beads)--she wouldn't have access, for complicated reasons related to the first set.
(I have--no idea how to search this one)
Edit: thanks, everyone! That was quick! (though if anyone wants to add more details/suggestions, feel free...)
