The impressive ceremonial of initiating the youth into the order of
the Kōk-kō occurs but once in four years. No male child above the
age of four years may, after death, enter the Kiva of the Kōk-kō
unless he has received the sacred breath of the Kōk-kō. Those who
personate the Kōk-kō are endowed for the time being with their
actual breath. Besides the Sä-lä-mō-bī-ya of the North, West,
South, East, Heavens, and Earth, and a number of younger brothers who
appear on this occasion, there are Pā-oo-tī-wa (Plate XX), father of
the Sun, ten Kō-yē-mē-shi, and the Kō-lō-oo-wĭt-si.

The Sä-lä-mō-bī-ya of the North wear yellow (hlūp-si-na) masks;
those from the West, blue (hli-än-na); those from the South, red
(shi-lō-ā); those from the East, white (kō-hān); those from the
Heavens, all colors (ī-tō-pō-nän-ni); those from the Earth, black
(quin-nā). (Plate XXI.) These colors represent the cardinal points,
the zenith, and the nadir:

North. Yellow. Hlūp-si-na.
West. Blue. Hli-än-na.
South. Red. Shi-lō-ā.
East. White. Kō-hān.
Heavens. All colors. ī-tō-pō-nän-ni.
Earth. Black. Quin-nā.
