Shivalaya is a gurukul, that give vedic education to life as Sanatan Dharma says. It is basically gives a transition way of life between the present life style to the vedic so that society easily move towards vedic without any stress.

Varna Vidhi is the caste system that people understand nowadays. Varna Vidhi is not the category we do, it has its own natural form. What any human will do is already shown by their body and mind and they act accordingly. And you can see that there are only four types of important categories in the society, Administration type, Teaching type, Management type, and Service type. So in our Sanatan Dharm, these types of categories have been created according to what a person will do.
