expressions of Brahminical yoga thought is the Yoga Sutras of Patanjali (early centuries CE, the original name of which may have been the Pātañjalayogaśāstra-sāṃkhya-pravacana (c. 325–425 CE); some scholars believe that it included the sutras and a commentary. As the name suggests, the metaphysical basis of the text is samkhya; the school is mentioned in Kauṭilya's Arthashastra as one of the three categories of anviksikis (philosophies), with yoga and Cārvāka.Olivelle, Patrick (2013), King, Governance, and Law in Ancient India: Kautilya's Arthasastra, Oxford University Press, , see Introduction Yoga and samkhya have some differences; yoga accepted the concept of a personal god, and Samkhya was a rational, non-theistic system of Hindu philosophy. Patanjali's system is sometimes called "Seshvara Samkhya", distinguishing it from Kapila's Nirivara Samkhya. The parallels between yoga and samkhya were so close that Max Müller says, "The two philosophies were in popular parlance distinguished from each other as Samkhya with and Samkhya without a Lord." Karel Werner wrote that the systematization of yoga which began in the middle and early Yoga Upanishads culminated in the Yoga Sutras of Patanjali. The Yoga Sutras are also influenced by the Sramana traditions of Buddhism and Jainism, and may be a further Brahmanical attempt to adopt yoga from those traditions. Larson noted a number of parallels in ancient samkhya, yoga and Abhidharma Buddhism, particularly from the second century BCE to the first century AD. Patanjali's Yoga Sutras are a synthesis of the three traditions. From Samkhya, they adopt the "reflective discernment" (adhyavasaya) of prakrti and purusa (dualism), their metaphysical rationalism, and their three epistemological methods of obtaining knowledge. Larson says that the Yoga Sutras pursue an altered state of awareness from Abhidharma Buddhism's nirodhasamadhi; unlike Buddhism's "no self or soul", however, yoga (like Samkhya) believes that each individual has a self. The third concept which the Yoga Sutras synthesize is the ascetic tradition of meditation and introspection. Patanjali's Yoga Sutras are considered the first compilation of yoga philosophy. The verses of the Yoga Sutras are terse. Many later Indian scholars studied them and published their commentaries, such as the Vyasa Bhashya (c. 350–450 CE). Patanjali defines the word "yoga" in his second sutra, and his terse definition hinges on the meaning of three Sanskrit terms. I. K. Taimni translates it as "Yoga is the inhibition () of the modifications () of the mind ()". Swami Vivekananda translates the sutra as "Yoga is restraining
