1. Human life begins with varnasrama

    You cannot change. Simply by acting in devotional service, bhagavata dharma, anyone can be raised to the highest position. Kirata-hunandhra-pulinda-pulkasa abhira sumbha yavanah khasadayah ye ‘nye ca papa (SB 2.4.18). Papa, these are papa. Papa means very abominable life. Even they can be raised to the highest perfection. Mam hi partha vyapasritya ye ‘pi syuh papa-yonayah (BG 9.32). The papa-yoni. Papa-yoni, there are different types of papa-yoni. Except civilized human being, advanced human being, those who are called Aryan. Aryan means those who are advanced. Below that position they are all papa-yoni. In the Aryan civilization there is a system of four divisions of social order and four division of spiritual order. Social order is brahmana, ksatriya, vaisya and sudra. And spiritual order: brahmacari, grhastha, vanaprastha and sannyasa. Therefore what is going on at the present moment as Hindu… This word you won’t find in the Vedic literature. Varnasrama. This is real Vedic system, varnasrama. And human life begins when one observes the varnasrama regulations. Varnasrama. Human life means to elevate oneself to spiritual consciousness or God consciousness.
