Ka
The basic visual representation of the Ka, a pair of raised arms. [1]
In religio-mythology, Ka, one of the seven main parts (see: Egyptian model of human) of the human in Egyptian mythology (compare: ba), the precursor to the Christian concept of the spirit, is a thing conceptualized as []; oft-depicted as a pair of arms raised.

Overview
In 1978, Anthony Mercante, in his Who’s Who in Egyptian Mythology, a basic dictionary of sorts, defined Ka as follows: [1]

KA: The double or the abstract personality of a man or woman. The Ka could separate itself from or unite itself to the body at will and could move freely from place to place. A dead man's Ka had to be preserved if his body was to become everlasting. Funeral offerings, such as meats, cakes, wines, and unguents, were made to the Ka, and when food was not available, offerings were painted on the walls, accompanied by the recitation of specific prayers. The tombs of the early Egyptian had special chambers in which the Ka was worshiped and received offerings, and the priesthood included a group called "priests of Ka," who performed services in honor of the Ka. According to one version of the creation myth that appears in the Pyramid Texts, after the sun god spit the gods Shu and Tefnut, he put his arms about them so that his "Ka might be in them." The Ka is closely associated with the Ba, the soul.”

Quotes
The following are related quotes:

“As their lives and loves survive in memory among their offspring, their ka souls will continue to shine from the shadow play among the ba structures of this book.”
Karl Luckert (1991), “In Memory” of father Wilhelm G. Luckert, whose “restless mind harbored questions and doubts which the Karl imbibed in childhood”, and mother Emilie Luckert-Hilt, who passed while book was going to press; note: he seems to have “ka” associated with soul, whereas correctly the “ba” is typically translated as soul [2]
