ADVAITA MEDITATION V: You exist only in God

Hindu philosophy is divided into orthodox (astika) and heterodox (nastika). The orthodox accept the authority of the Vedas and the Upanishads while the heterodox philosophical systems deny Vedic authority. The orthodox schools generally include six darśanas (view of the divine): Nyaya Vaisheshika Samkhya Yoga Mīmāṃsā and Vedanta and the common heterodox schools are Jainism Buddhism Ajñana Ajivika and Lokaiata.The authors of the darsanas are: Vedanta (by Viasa) Yoga (by Patañyali) Sankhia (by Kapilá) Mimansa (by Yaimini) Niaiá (by Gótama) Vaisesika (by Kanada). They complement each other in pairs: nyāya and vaiśeṣika sāṃkhya and yoga mīmāṃsā and vedānta.Vedanta (end of the Vedas) is based on the main Upanishads the Brahma Sutras and the Bhagavad Gita. There are three main schools within Vedanta which base their doctrine on the Upanishads: Advaita (non-dualistic) whose main exponent is Shankara (7th century); Advaita Visista (qualified non-dualistic) whose main exponent is Ramanuja (10th century); and Dvaita (dualistic or pluralistic) whose main exponent is Madhava (11th century).
