The Vedic culture determines the standard of social upliftment in terms of the degree of self-realization and as such the social division was estimated accordingly in terms of goodness (intelligence and higher learning), passion (martial spirit to lord it over the world), passion-cum-ignorance (the spirit of productivity) and ignorance (the spirit of passive acceptance of being controlled by the laws of material nature).
According to Vedic scriptures the present age is called Kali-yuga and almost all human beings are now degraded to the standard of the mode of ignorance and therefore the greater number of population are subjected to the pangs of the threefold miseries of material existence in the most horrible manner.
