Bhakti yoga claims the most accessible entry point to the divine: love. Where Jnana Yoga requires fierce discriminative intellect and Raja Yoga requires years of disciplined meditation, bhakti asks only that the heart be pointed.
Its methods are devotional: Kirtan (call-and-response singing), Japa (repetition of divine names), image-based worship, pilgrimage, the company of the awakened (Satsang), and above all Surrender.
Mirabai, Kabir, chaitanya, Ramakrishna — each a master of this path. In the Bhagavad Gita Krishna declares bhakti the most accessible of the yogas. It remains the most widely practiced in South Asia.
