Adi Shankara also authored the Vivekachudamani, 581 verses spelling out the qualifications required in a student of Vedanta: to be able to discriminate between the real and the unreal; to be able to maintain a spirit of detachment from this world; to have the capacity to control sensory perceptions; and to feel an intense desire to attain self-realization and moksha. The Vivekachudamani reviews the entire range of Hindu philosophical thought and argument, from the Upanishads to the Bhagavad Gita.
