Yes, cows are holy indeed.
Reasons to keep a cow in a family:

1. Cows maintain a spiritual environment in a family; it means less stress, prevalence of love, care, and understanding amongst family members. It has been proved and verified that a person who stays in the vicinity of a cow for 30 minutes everyday will effortlessly and unknowingly develop positive attitude, intellect and righteousness; in a research, results were seen clearly in a period of two to six months.

2. Cows help maintain a healthy environment. If a person has problems of blood pressure and sugar levels, he should rub his hands on the cow’s hump for 15 minutes everyday. In six months time, the patient will be cured completely. It is not clear how many other diseases can be cured this way; more research is underway.

3. Cow’s dung and urine have numerous medicinal values; a 90 year old man testifies the fact saying that he had never took any medicines in his entire life other than cow’s urine for all diseases. At 90, he’s as healthy as a youth.

4. Cow dung produced by just two cows is sufficient to produce enough bio-gas for cooking, and lighting a 60 W lamp for a four-member family. The dung-slurry which is a waste from the fermentation serves as a rich natural manure for farming.

5. A family that gets to drink enough cows’ milk will not suffer from malnutrition; cow’s milk and its products have high nutritional value. The milk can also be sold for additional income.

6. The Vedas regard a cow’s body as the dwelling of the Gods and Goddesses in subtle form; since I cannot provide proof of this, I shall not debate on it. Based on the above facts, I will just conclude that a cow does hold positive energy in her.

Unfortunately, the world has been killing “Goumata” (Mother Cow) for beef. There’s no need to explain what we’ve achieved or where the world has reached by doing so- unrighteous people, greed, disease, hatred, poverty, malnutrition,………. We all know !
