Pancadasi is a prakarana grantha, a book of definition for the students to again a better understanding of the import of the Upanishads. It gives precise logic and clears various doubts regarding Vedanta. It is regarded highly amongst the vedantins. Its study is sufficient by itself and can take the seekers to the peaks of knowledge.
It has fifteen chapters and hence is called Pancadasi. It is roughly speaking the first five chapters (viveka prakaranas) talk of the discrimination of the real and the unreal (sat-vidya). The next five (dipa prakaranas) deal with the awareness aspect of Reality (cit-Vidya). The last five (Ananda prakaranas) deal with the Bliss aspect (Ananda-Vidya). However, each chapter is complete in expounding the Truth.
