dojo

a place of learning
a time for focused practice
to gain mastery

A dōjō (道場) is a hall or space for immersive learning or meditation. This is traditionally in the field of martial arts, but has been seen increasingly in other fields, such as meditation and software development. The term literally means "place of the Way" in Japanese.

kintsukuroi

once the potter’s clay
the vase already broken
perhaps by design  

Kintsugi (金継ぎ, "golden joinery"), also known as Kintsukuroi (金繕い, "golden repair"),

is the Japanese art of repairing broken pottery with lacquer dusted or mixed with powdered gold, silver, or platinum, a method similar to the maki-e technique.

As a philosophy, it treats breakage and repair as part of the history of an object, rather than something to disguise.
