The *Panchadasi* , written by Swami Vidyaranya, is a foundational text of Advaita Vedanta that systematically explains the nature of ultimate reality ( Brahman ), the individual self ( Atman ), and the illusory world ( Maya ). Divided into 15 chapters, it explores the discrimination of reality, the illumination of truth through meditation, and the bliss that arises from Self-realization. Combining philosophy, logic, and spiritual practice, the text serves as a guide for seekers to understand and experience the unity of the self with the infinite Brahman, leading to liberation ( moksha ).
