11th-century Indian philosophers

Ramanuja ('; Middle Tamil: Rāmāṉujam; Classical Sanskrit: Rāmānuja; 1077 – 1157, trad. date 1017-1137), also known as Ramanujacharya''', was an Indian Hindu philosopher, guru and social reformer. He is one of the most important exponents of the Sri Vaishnavism tradition in Hinduism. His philosophical foundations for devotional practice were influential in the Bhakti movement.

Abhinavagupta (Devanāgarī अभिनवगुप्तः; c. 950 – 1016 CE) was a philosopher, mystic and aesthetician from Kashmir. He was also considered an influential musician, poet, dramatist, exegete, theologian, and logician – a polymathic personality who exercised strong influences on Indian culture.

Nāropā (c. 1016 - 1100 CE) (Prakrit; , Naḍapāda or Abhayakirti) was an Indian Buddhist Mahasiddha. He was the disciple of Tilopa and brother, or some sources say partner and pupil, of Niguma. As an Indian Mahasiddha, Naropa's instructions inform Vajrayana, particularly his six yogas of Naropa relevant to the completion stage of anuttarayogatantra. He was also one of the "gatekeepers" of Vikramashila monastery and was also associated with Nalanda monastery where he rose to the position of abbot.
