White Copper Agate Acala Pendant

The immovable in Acala's name refers to the mind, not to a body that does not move. He is the command manifestation of Vairocana, first of the five great vidyarajas, and his form is wrathful: a sword raised in the right hand, a noose gripped in the left, a ring of flame at his back. The sword cuts through affliction, the noose binds beings too stubborn to be tamed any other way, and in paintings those two implements usually show up more plainly than the face. Whoever cuts the die knows where the weight belongs. Each of the five vidyarajas guards a direction, and Acala holds the centre.

A wrathful face is hard to make. Brows squeeze together, teeth clamp, flames lick upward one tongue at a time; cut it shallow and he looks like someone losing his temper, cut it deep and the face turns into slabs of muscle. These plaques are relief, and the planes can be layered: the face in front, the flames a layer behind, sword and noose crossing in between, so a glance around the eyes reads distance. Polished highlights are kept for the forehead and the ridge of the sword; everything else stays matte from the cast, and that is what keeps the ferocity sunk in the metal instead of floating on the surface. The thickness of the copper plays a part here too. Too thin and the relief cannot rise; too thick and it drags at the neck.

Agate is harder than copper, so when it is set into copper a knock chips the stone, not the metal. On pieces with agate the corners are therefore wrapped and the exposed edges are kept blunt. Agate is banded, one layer dark and the next pale, and the colour shifts with the angle of the cut, so two pieces of the same design set side by side can differ by a good stretch of red. That is not a fault. What you watch for is cracking: fine fissures that follow the banding and catch a fingernail as it passes. Run a nail over the stone when you choose; it tells you more than a long look. Stone and copper expand at different rates, so the setting loosens a little in heat and in cold, and that is worth bearing in mind.

In Han regions the vidyarajas are less familiar than Guanyin, so ask before giving one. In Tibetan practice Acala is a protector, not an all-purpose charm for safe keeping, and it is more honest to say he holds a room steady than to say he answers every request. Take it off to bathe: agate dislikes sudden heat and cold, and it dislikes soap drying in the crevices. Store it in its own bag rather than heaped with other jewellery, since agate suffers most from grinding against harder things. If you keep it for veneration, what is venerated is the meaning, not this piece of copper.

The two versions differ at the chain. On the single plaque you fit your own cord, waxed or leather, and a thicker cord carries the weight better; the version with a chain is wearable straight out of the box, but the look is settled for you. On a slender neck, do not let the plaque hang too low. Set it just above the breastbone and it will not swing as you walk or turn over on itself. Choose a lobster clasp over a spring clasp, which weakens with use. Finish cord ends over a flame and press them flat, or the tips will fray apart.
