Lord Shiva is always in the company of a Bull
Lord Krishna is always in the company of Cows
It  has a deeper meaning & message to us!

Nandi is a symbol  of a life energy, manifestation power –vitality, strength, faith and consistency.
Cows & Bulls being slaughtered is a sign of demonic civilization! We have to change this trend, Protecting Cows & Bulls means keeping  this planet safe & conserved for our children!
It's the greatest service to Mankind!
