"Heka was seen as a gift from the sun god Re to mankind (his offspring), a manifestation of his creative energy as an embodiment of his Ba (his soul). It empowered man to create using words and actions, mirroring the sun god's creation of the universe. Heka can be seen as the creative force or life-giving energy connecting the objects, links and symbols of life with the universe, like a subtle tapestry of energy, which the magician must learn to read if s/he is to effectively work magic."
From the book "Heka" by David Rankine
