Varnashrama system is not meant to divide society, but to unite it for the higher purpose of serving Krishna. It gives each person an opportunity to serve according to their nature. The four classes - Brahmanas, Kshatriyas, Vaishyas, and Shudras - each have specific duties suited to their qualities and natures, with the ultimate goal of pleasing Krishna. Brahmanas cultivate peacefulness and wisdom, Kshatriyas heroism and leadership, Vaishyas farming and business, and Shudras serve others. One's class is determined by qualities, not birth alone.
