much reverence for cows.  According to what I learned after reading the article recently. Many people including myself and yourself had a lot of misconceptions about Hinduism.  It is not that they worship cows OK.  

Hindus do not worship cows. This common misconception is due to the manner in which Hindus treat the cow, an animal that gives more than it takes, is symbolic of all other animals, and represents life and the sustenance of life. Taking only grain, grass, and water, a cow provides milk, cream, yogurt, cheese, butter, and fertilizer for the fields—thus giving more than it takes.

Cows are also respected for their gentle nature and are seen as maternal caretakers. Because of how venerated cows are in Hinduism and Indian society, it appears to outsiders that they are worshiped. But Hindus see it as honoring and respecting the animals instead.
