For centuries, the gender discrimination has been prevalent in Indian society. When it is about the Dalit community, the woman is marginalized thrice, in terms of caste, class and gender. Writing an autobiography is a special act for these women writers who use the genre to achieve a sense of identity and resistance against different forms of oppression. As a Dalit Christian Bama depicts her existential predicament: her struggle against patriarchy, class, caste and religion in her autobiographical text, Karukku, which is considered as the first autobiography written by a Dalit Christian woman. In her writings, Bama brings all the marginalized identities- Tamil, Dalit, Christian and Woman- under single canopy with synonymous understanding which challenges the mainstream aesthetic and reveals the real sufferings of a self as well as community. The present paper brings forth the subversive quality of Dalit women’s writings that not only challenge a caste-stratified social system but also defies the patriarchal domination that exists both within and outside Dalit community. Bama’s autobiographical text is thus studied as a counter-narrative to the mainstream literature to understand the multiple ways in which the issues of caste, gender and class intersect with each other, and how intersectionality and feminist stand point offer an effective analytical tool to study the text. Such an intersectional analysis in the context of gender, caste and class, has been done in the present paper. This paper also proposes to explore how Bama’s writing compels readers to acknowledge the gaps in the existing body of “Indian Knowledge”. Her writing also urges to consider how a more inclusive understanding of Indian society requires incorporating the perspectives and experiences of marginalized communities. Karukku stands as a pivotal work in Dalit literature and feminist discourse, voicing the unique experiences and struggles of Dalit women. Bama’s journey in the autobiographical work is a quest for self-discovery and reclaiming agency, enabling her to challenge dominant narratives and assert her rights.
