<P> Both Sāmkhya and Yoga systems of religious thought are mokshaśāstras, suggests Knut Jacobsen, they are systems of salvific liberation and release . Sāmkhya is a system of interpretation, primarily a theory about the world . Yoga is both a theory and a practice . Yoga gained wide acceptance in ancient India, its ideas and practices became part of many religious schools in Hinduism, including those that were very different from Sāmkhya . The eight limbs of yoga can be interpreted as a way to liberation (moksha). </P> <P> In Sāmkhya literature, liberation is commonly referred to as kaivalya . In this school, kaivalya means the realization of purusa, the principle of consciousness, as independent from mind and body, as different from prakrti . Like many schools of Hinduism, in Sāmkhya and Yoga schools, the emphasis is on the attainment of knowledge, vidyā or jñāna, as necessary for salvific liberation, moksha . Yoga's purpose is then seen as a means to remove the avidyā - that is, ignorance or misleading / incorrect knowledge about one self and the universe . It seeks to end ordinary reflexive awareness (cittavrtti nirodhah) with deeper, purer and holistic awareness (asamprājñāta samādhi). Yoga, during the pursuit of moksha, encourages practice (abhyāsa) with detachment (vairāgya), which over time leads to deep concentration (samādhi). Detachment means withdrawal from outer world and calming of mind, while practice means the application of effort over time . Such steps are claimed by Yoga school as leading to samādhi, a state of deep awareness, release and bliss called kaivalya . </P> <P> Yoga, or mārga, in Hinduism is widely classified into four spiritual practices . The first mārga is Jñāna Yoga, the way of knowledge . The second mārga is Bhakti Yoga, the way of loving devotion to God . The third mārga is Karma Yoga, the way of works . The fourth mārga is Rāja Yoga, the way of contemplation and meditation . These mārgas are part of different schools in Hinduism, and their definition and methods to moksha . For example, the Advaita Vedanta school relies on Jñāna Yoga in its teachings of moksha . </P> <P> The three main sub-schools in Vedanta school of Hinduism - Advaita Vedanta, Vishistadvaita and Dvaita - each have their own views about moksha . </P>
