White Mirror is the eighteenth Solar Seal, white and of the north in Arguelles's rotation, and it opens the fourth wavespell. Its stated triad is endlessness as its power, reflecting as its action and order as its essence, and it is read in Dreamspell practice for truthfulness, for seeing things as they are and for the cutting away of what is false. The mirror imagery is Arguelles's extension of an underlying sign whose meaning is sharper and more concrete.
In the Dreamspell tradition, White Mirror, Solar Seal 18, is described as governing order, endlessness and reflective clarity, built from the mirror half of Etznab's borrowed imagery. White Mirror belongs to the Dreamspell's White colour family, alongside White Wind, White Worldbridger, White Dog and White Wizard. The flint-blade, ritual-bloodletting associations Tijax carries in the living K'iche' tradition are not part of the Dreamspell's own gloss for this seal. Its Dreamspell wavespell is the eighteenth of twenty. Order and endlessness, the seal's Dreamspell gloss, draw on the mirror half of Etznab's paired imagery while setting aside the flint-blade, ritual-bloodletting associations the same sign carries within the authentic Tzolk'in tradition this atlas describes on its Tzolk'in day-sign pages.
