Vivekachudamani
The Vivekachudamani ( Sanskrit: विवेकचूडामणि) is a famous Sanskrit poem ascribed to Adi Shankara in the eighth century. It expounds the Advaita Vedanta philosophy and is in the form of 580 verses in the Shardula Vikridita metre. The Vivekachudamani describes developing Viveka, the human faculty of discrimination or discernment between real (unchanging, eternal) and unreal (changing, temporal), as the central task in the spiritual life, and calls it the crown jewel among the essentials for Moksha. The title Vivekachudamani translates to Crest Jewel of Discrimination. Through the centuries, the Vivekachudamani has been translated into several languages and has been the topic of many commentaries and expositions.
