Traditional Panchadasi or Panchadashi (Devanagari: पञ्चदशी IAST paṃcadaśī) is a simple yet comprehensive manual of Advaita Vedanta written in the fourteenth century CE (1386-1391) by Vidyaranya, previously known as Madhavacharya.
It elaborates Advaita (non dual), Consciousness, Jiva, Maya, Prakriti (Prakṛti, Nature[5]), Mahat (universal mind), Buddhi (Intellect), Ahamkara (Ego), Avidya (Ignorance), and ananda (Bliss).
[4] Vidyaranya also wrote Drk-Drsya-Viveka, Sarvadarsana Samgraha, Sri Sankara Digvijaya, Jivanmukti Viveka, Anubhuti Prakasa, Vivaranaprameyasamgraha and Upanishad Dipika[13] has been identified with Sayanacharya, the commentator on the Vedas, whose brother he most likely was.
The purpose of the life is the realization of the experience of Absolute Existence, which is the highest fulfillment all the aspirations of the whole of creation.
Vidyaranya has succeeded in an eminent way in setting forth the essentials of Advaita which holds that the direct means to release is the path of knowledge (jnana), and as moksa is the very nature of the Self, it is not an experience which is to be brought about through works (karma) ".
