Bhakti yoga (Devanāgarī: भक्ति योग) is a spiritual path described in Hindu philosophy which is supposed to be for fostering love, utter faith and surrender to God. It is a means to realize God, and is the easiest way for the common person because it doesn't involve extensive yogic practices.

The Bhagavad Gita, Bhagavata Purana and Puranas are important scriptures which expound the philosophy of Bhakti. Hindu movements in which bhakti is the main practice are called bhakti movements—the major schools are Shaivism, Vaishnavism, and Shaktism.

Bhakti is a Sanskrit term that signifies an attitude of devotion to a personal God that is similar to a number of human-human relationships (difference is that in bhakti relationships is soul-Supersoul, soul-God) such as beloved-lover, friend-friend, parent-child, and master-servant.

The Bhagavata Purana teaches nine primary forms of bhakti, as explained by Prahlada:

(1) śravaṇa ("listening" to the scriptural stories of Kṛṣṇa and his companions), (2) kīrtana ("praising," usually refers to ecstatic group singing), (3) smaraṇa ("remembering" or fixing the mind on Viṣṇu), (4) pāda-sevana (rendering service), (5) arcana (worshiping an image), (6) vandana (paying homage), (7) dāsya (servitude), (8) sākhya (friendship), and (9) ātma-nivedana(complete surrender of the self). (from Bhagata Purana, 7.5.23-24)
