Vivekachudamani is a Sanskrit text written by the Indian philosopher Adi Shankaracharya in the 8th century. The title translates to "Crest-Jewel of Discrimination" and the text deals with the Vedantic philosophy of Advaita Vedanta, which asserts that the individual self (jivatman) and the ultimate reality (Brahman) are ultimately identical.

The text consists of 580 verses and is written in the form of a dialogue between a teacher and a student. The teacher explains the nature of the ultimate reality, the path to realizing it, and the obstacles that one may face along the way. The text also emphasizes the importance of renunciation and spiritual practice in attaining liberation from the cycle of birth and death.

Vivekachudamani is considered one of Shankaracharya's most important works and has been widely studied and commented upon by scholars of Indian philosophy. It is considered a foundational text in the Vedantic tradition and has been highly influential in shaping Hindu thought and practice.
