Popular shorthand often flattens cow reverence into a single generic idea, "the sacred cow," but the traditions that actually hold cattle in high regard do not agree on why or how. Contemporary Hindu practice, particularly in India, generally treats cow protection as an ethical and religious commitment tied to the animal's association with nurturing and with several deities, most directly Krishna in his cowherd aspect, and this has become both a devotional practice and, in the modern period, a politically contested one, entangled with questions of diet, law and communal identity that go well beyond the ancient textual sources.
Ancient Egyptian cow symbolism, by contrast, was a matter of temple cult and royal iconography rather than a rule governing everyday treatment of livestock; cattle were herded, milked and eaten in ancient Egypt without contradiction, while the cow as symbol stood apart in Hathor's and Nut's divine imagery. Treating the two traditions as one continuous idea rather than two separate developments risks projecting a modern Indian religious and political question backward onto an unrelated ancient Egyptian cult.
