Karma Yoga

Karma Yoga, or the "discipline of action" is based on the teachings of the Bhagavad Gita, a holy 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) by doing his duties in an unselfish manner.
Per Hinduism, the gist of mundane life centres on Karma. It is believed that a man is born with certain Sanskars, his past pushes him towards doing certain Karma and these Karmas are then deposited in his virtual account. The process continues until the individual attains a zero balance, wherein one achieves liberation from the cycle of rebirth.

Following the practice of Karma yoga, an individual can potentially become a true spiritual seeker and realize his true nature as Atman. He can live in & work for this world but still remain untouched by the grossness of mundane pleasures.
