Aparokshanubhuti
The Aparokshanubhuti ( Sanskrit: अपरोक्षानुभूतिः) is a famous work attributed to Adi Shankara. It is a popular introductory work that expounds Advaita Vedanta philosophy. It describes a method that seekers can follow to directly experience the essential truth of one's one nature. Thus, the work is literally titled Aparokshanubhuti, or Direct Experience. Swami Vimuktananda titles his translation Self-Realization.
