The resonance matching got cleaner over the next few days.
Not fast, not dramatically, just the steady accumulation of repetition doing what repetition did when you were paying attention.
The match came quicker each morning, the sympathy feeling in his chest easier to locate and easier to trust, and by the fourth day of the exercise he could produce a clean resonant match on the new stone within the first two or three attempts instead of spending half the session finding it.
Dian introduced a third stone on the fifth day. Then a fourth two days after that. Different compositions, different core frequencies, each one requiring him to start from scratch on the listening and work his way down to the core before he could match it.
The process was faster now than it had been with the first stone, which apparently happened naturally once you understood what you were looking for, but each new stone still had its own particular quality that couldn't be assumed from the ones before it.
