The music is a mathematical representation of intersecting fields, as is the title. In cooking, the field of the kitchen intersects and interacts with the literal field where food is grown. That is, mathematically, the overlapping of two (or more) functions in three dimensions. So to, in the music, the planes of the gong and bass intersect via the subwoofer resonating the gong. Simultaneously, in the kitchen Evans manifested the intersecting fields by preparing food including ingredients he grew himself in the garden, its own performative action.
“A parent protects their child from heat or cold before worrying about whether they themselves are hot or cold. This kind of care can only be understood by those who have given rise to it and realized only by those who practice it. This, brought to its fullest, is how you must care for water and rice, as though they were your own children.” – Dogen Zenji, Instructions for the Tenzo, 1237
