It is said that Dharma has four legs (pillars) and it is depicted in the form of vrushabham (nandi). What are those four legs? AFAIKAs far as I know, cow's four legs are also seen as four legs of Dharma.
Dharma has 4 legs in Satya yuga, 3 in Treta, 2 in Dwapara and just 1 leg in Kali yuga. How to understand this?
Does it merely mean the percentage of righteousness in an individual, righteous people in a society or a theoretical combination of some practices?
