Yoga is more than just a physical exercise. The word ?yoga? comes from the Sanskrit root Yuj which means to link up with, or combine. Bhakti is derived from the Sanskrit word bhaj, which means ? loving service. Bhakti-yoga means to connect to the Supreme by means of loving devotional service. The Bhagavad Gita, the core spiritual text for KRISHNA, describes variety of yoga practices. Among them are karma-yoga (the practice of conscious action), jnana-yoga (philosophical study and contemplation), and hatha-yoga (the practice of yoga-asanas and breathing exercises). Today, some yoga practitioners consider the physical benefits of yoga to be the end in themselves. But according to the traditional yoga systems, physical exercises are just one step on path of God realization. The Gita ultimately prescribes bhakti-yoga (the path of dedication and love) as the culmination of other yoga practices. Bhakti-yoga focuses on developing our dedication, service and love for the Divinity, Lord Krishna.
