Yoga Vasishtha
Yoga Vasishtha (Sanskrit: योगवासिष्ठम्, IAST: yoga-vāsiṣṭham; also known as Mokṣopāya or Mokṣopāyaśāstra, and as Maha-Ramayana, Arsha Ramayana, Vasiṣṭha Ramayana, Yogavasistha-Ramayana and Jnanavasistha, is a historically popular and influential syncretic philosophical text of Hinduism, dated to the 11th to 14th century CE. According to Mainkar, writing in 1977, the text started as an Upanishad, which developed into the Laghu Vasistha, incorporating Buddhist ideas, and then, between 1150 and 1250, the Yoga Vasistha, incorporating Shaivite Trika ideas. According to Slaje, writing in the 2000s, the Mokṣopāya was written in Kashmir in the 10th century.
