Unraveling Prapañca: A Yogācāra Examination of Consciousness, Language, and Liberation in the Laṅkāvatāra Sūtra

In Yogācāra epistemology, the term prapañca refers to various dimensions of the cognitive process in aspects ranging from consciousness, language formation, the conceptualization of subject–object duality, mental defilements, and ignorance. Given that the Laṅkāvatāra Sūtra conveys the richness of early tenets for both the Yogācāra and Madhyamaka traditions, an investigation of the meaning and discourse context of prapañca is a necessity. This paper conducts a contextual examination of the word prapañca, primarily addressing (1) a range of meanings, (2) possible characteristics, (3) conditions and consequences, especially the associations with the conceptualization (vikalpa) process, and (4) the significance of the elimination of prapañca that the corresponding dialogue implies. This paper finds that prapañca is associated with dualistic conceptualization and the evolution of consciousness within saṃsāra. It shows some qualities of the beginningless conceptual structure of saṃsāric conditioned negativity and is related to language formation. As the discourse in Laṅka adduces it as the root of suffering, liberation from it is a prerequisite for reaching enlightenment and achieving the state of Buddhahood.
