This caste system had grown by the practice of the son always following the business of the father.
Swami VivekanandaWhere will you go to seek Brahman? He is immanent in all beings. Here, here is the visible Brahman! Shame on those who, neglecting the visible Brahman, set their minds on other things! Here is the visible Brahman before you as tangible as a fruit in one's hand! Can't you see? Here - here - is Brahman!
Swami Vivekananda
