Book excerpt: Although there are many types of yoga practice, the Vedic literature explains that no matter which practice you choose, success is only achieved when bhakti is present. What is bhakti-yoga, and how can you add it to your life or your current yoga practice? As bhakti is a pivotal element in any yogic or religious practice, it is known as the topmost yoga. In the Bhagavad-gita, Krishna explains bhakti-yoga to his dear friend Arjuna, and here Srila Prabhupada expands these concepts in this introductory text.
