An important part of the Egyptian soul was thought to be the Ib (jb), or heart. The Ib or metaphysical heart was believed to be formed from one drop of blood from the child's mother's heart, taken at conception.
To ancient Egyptians, the heart was the seat of emotion, thought, will and intention. This is evidenced by the many expressions in the Egyptian language which incorporate the word ib, Awt-ib: happiness (literally, wideness of heart), Xak-ib: estranged (literally, truncated of heart). This word was transcribed by Wallis Budge as Ab.
In Egyptian religion, the heart was the key to the afterlife. It was conceived as surviving death in the nether world, where it gave evidence for, or against and its possessor. It was thought that the heart was examined by Anubis and the deities during the Weighing of the Heart ceremony. If the heart weighed more than the feather of Maat, it was immediately consumed by the monster Ammit.
(This all fictions descriptions of jw,yw are nonsense)
Basis on phonetic 'jb' and logogram, it is the Sanskrit word yh +wh ;% o% (;g og), which mean 'speedy + air'(tornado) respectively. The hieroglyph presents a clear view of a tornado, cyclone, storm, hurricane', not as is stated 'heart'.
The Hebrews could not know their God, how can the Europeans understand it? The word 'YhWh', which means a tornado or speedy air, is none but the angry god of Hebrews. Later the word yhwh became being corrupt as yhwh >hwh >hwa, which was used for 'air' in Semitic languages.
