Scholars in Kerala have identified a significant 12th-century manuscript titled 'Karuna-Vritti-Sagara' (The Ocean of Compassionate Conduct). This work provides an exhaustive philosophical treatment of Karuna (compassion) not merely as an emotion, but as a foundational metaphysical principle that binds all sentient life together in a web of mutual resonance and responsibility.
The text is notable for its integration of early Advaita logic with the ethical imperatives of the Bhakti movement. It argues that the perception of 'Oneness' is logically incomplete without the practice of radical empathy. This discovery offers new insights into how Sanatan Dharma evolved to address social disparities through a lens of philosophical monism and compassionate action.
