Bhakti (भक्ति) means "attachment, participation, fondness for, homage, faith, love, devotion, worship, purity". It was originally used in Hinduism, referring to devotion and love for a personal god or a representational god by a devotee. In ancient texts such as the Shvetashvatara Upanishad, the term simply means participation, devotion and love for any endeavor, while in the Bhagavad Gita, it connotes one of the possible paths of spirituality and towards moksha, as in bhakti marga.
Bhakti in Indian religions is "emotional devotionalism", particularly to a personal god or to spiritual ideas. Thus, bhakti requires a relationship between the devotee and the deity. The term also refers to a movement, pioneered by Alvars and Nayanars, that developed around the gods Vishnu (Vaishnavism), Shiva (Shaivism) and Devi (Shaktism) in the second half of the 1st millennium CE.
Bhakti ideas have inspired many popular texts and saint-poets in India. The Bhagavata Purana, for example, is a Krishna-related text associated with the Bhakti movement in Hinduism. Bhakti is also found in other religions practiced in India, and it has influenced interactions between Christianity and Hinduism in the modern era. Nirguni bhakti (devotion to the divine without attributes) is found in Sikhism, as well as Hinduism. Outside India, emotional devotion is found in some Southeast Asian and East Asian Buddhist traditions, and it is sometimes referred to as Bhatti.
The Sanskrit word bhakti is derived from the verb root bhaj-, which means "to worship, have recourse to, betake onself to" or bhañj-, which means "to break." The word also means "attachment, devotion to, fondness for, homage, faith or love, worship, piety to something as a spiritual, religious principle or means of salvation".
The meaning of the term Bhakti is analogous to but different from Kama. Kama connotes emotional connection, sometimes with sensual devotion and erotic love. Bhakti, in contrast, is spiritual, a love and devotion to religious concepts or principles, that engages both emotion and intellection.
