karma yoga

Karma yoga (Sanskrit: कर्म योग), (also known as Buddhi Yoga) or the "discipline of action" is based on the teachings of the Bhagavad Gita, a sacred Sanskrit scripture of Hinduism. One of the four pillars of yoga, Karma yoga focuses on the adherence to duty (dharma) while remaining detached from the reward. It states that one can attain Moksha (salvation) or love of God (bhakti) by performing their duties in an unselfish manner for the pleasure of the Supreme. Karma Yoga is an intrinsic part of many derivative types of yoga, such as Natya Yoga.

Karma Yoga (Sanskrit) [from karma action + yoga union] One of the methods or stages of yoga practice and training, involving attaining at-one-ment or union with the spiritual-divine essence within by means of unselfish action or works.

A discipline of work or "action." The goal is to achieve moksha through the elimination of one's karma through work, that is, involvement in life and business. Essentially, if a person can work without viewing the results of their efforts as one of their own, then the results cancel part of their karma rather than adding to it. One form of karma yoga works as a version of achieve bhakti yoga , in which a person's actions are seen as a form of love and devotion to a divine being. Another form works as a version of achieve jnana yoga , in which one becomes detached from the work's results as one enters a deeper experience of their Atman . For another explanation go here .
