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 ISKCON, 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).
