They came to establish the rule of the oppressed and the downtrodden.

This couplet speaks to a profound and hopeful vision: the coming of those who are dedicated to establishing a government or system led by the oppressed and marginalized, specifically the Dalits. It's about empowering communities who have historically faced hardship to take the reins, ensuring their voices are heard and their rights are upheld. This signifies a movement towards a more just and equitable society where the marginalized are no longer excluded but are central to shaping their own future and governance.
