The cow in the Hindu scriptures

Rig Veda

Cattle are one of the important animals, and several hymns refer to ten thousand and more cattle.^[6] Rig Veda 7.95.2. and other verses (e.g. 8.21.18) also mention that the Sarasvati region poured milk and clarified butter (ghee), indicating that cattle were herded in this region. RV 6.28 is called Cows. Text 3 speaks about safety of cows.
In the Rig Veda, the cows figure frequently as symbols of wealth, and also in comparison with river goddesses, e.g. in 3.33.1 cd,

Like two bright mother cows who lick their young, Vipas and Sutudri speed down their waters.

Atharva Veda

Cow's body is represented by various devas and other subjects.^[7]

Brahma-saṁhitā

In the Brahma-saṁhitā it is said that the Lord, Śrī Kṛṣṇa, in His transcendental abode Goloka Vṛndāvana, is accustomed to herding the surabhi cows.^[8]

Harivamsha

The Harivamsha depicts Krishna as a cowherd. He is often described as Bala Gopala, "the child who protects the cows." Another of Krishna's names, Govinda, means "one who brings satisfaction to the cows." Other scriptures identify the cow as the "mother" of all civilization, its milk nurturing the population. The gift of a cow is applauded as the highest kind of gift.
The milk of a cow is believed to promote Sattvic (purifying) qualities. The ghee (clarified butter) from the milk of a cow is used in ceremonies and in preparing religious food. Cow dung is used as fertilizer, as a fuel and as a disinfectant in homes. Its urine is also used for religious rituals as well as medicinal purposes. The supreme purificatory material, panchagavya, was a mixture of five products of the cow, namely milk, curds, ghee, urine and dung. The interdiction of the meat of the bounteous cow as food was regarded as the first step to total vegetarianism.^[9]

Puranas

Prithu chasing Prithvi, who is in the form of a cow. Prithu milked the cow to generate crops for humans.

The earth-goddess Prithvi was, in the form of a cow, successively milked of various beneficent substances for the benefit of humans, by various deities starting with the first sovereign Prithu milked the cow to generate crops for humans to end a famine.^[10]
Kamadhenu, the miraculous "cow of plenty" and the "mother of cows" in Hindu mythology is believed to represent the generic sacred cow, regarded as the source of all prosperity.^[11] All the gods are believed to reside in her body; a form of Kamadhenu often depicted in poster-art^[12][13]
In the Bhagavata Purana, Surabhi is the name of the cows which exist in the spiritual planets and are especially reared by Kṛṣṇa. As men are made after the form and features of the Supreme Lord, so also the cows are made after the form and features of the surabhi cows in the spiritual kingdom.^[14] According to smṛti regulation, the cow is the mother and the bull the father of the human being. The cow is the mother because just as one sucks the breast of one’s mother, human society takes cow’s milk. Similarly, the bull is the father of human society because the father earns for the children just as the bull tills the ground to produce food grains. Human society will kill its spirit of life by killing the father and the mother^[15]

Historical significance

This picture shows a pamphlet against traditional cow Sacrifice in ancient India by certain stratas of the Hindu society. The colour version ran by the Ravi Varma Press (c. 1912).

The reverence for the cow played a role in the Indian Rebellion of 1857 against the British East India Company. Hindu and Muslim sepoys in the army of the East India Company came to believe that their paper cartridges, which held a measured amount of gunpowder, were greased with cow and pig fat. The consumption of swine is forbidden in Islam. Since loading the gun required biting off the end of the paper cartridge, they concluded that the British were forcing them to break edicts of their religion.^[16]

Gau Mata

The cow has been a symbol of wealth since ancient days. However, they were neither inviolable nor revered in the same way they are today.
The cow was possibly revered because Hindus relied heavily on it for dairy products and for tilling the fields, and on cow dung as a source of fuel and fertilizer. Thus, the cow’s status as a 'caretaker' led to identifying it as an almost maternal figure (hence the term gau mata). In the olden days cattle being limited to select few fortunate folks, the cows enjoyed the status that gold or money enjoys today. In addition, it has been suggested by author and orator Terence McKenna that religious reverence for the cow is a result of early humankind's association of psilocybin mushroom with it, this association having developed as a result of the discovery of said mushrooms in the animal's excrement.^[3]
Hinduism is based on the concept of omnipresence of the Divine, and the presence of a soul in all creatures, including bovines. Thus, by that definition, killing any animal would be a sin: one would be obstructing the natural cycle of birth and death of that creature, and the creature would have to be reborn in that same form because of its unnatural death. Krishna, one of the incarnations of god in Hindu Mythology (Avatar), tended cows. The cow and bull represent the symbol of Dharma, reverence for cows and bull is the major texts of the Vedic religion.^[4]
In South India and some parts of Sri Lanka, Cattle festival is celebrated and it is called as
