Bhakti (Sanskrit: भक्ति; Pali: bhatti) is a concept common in Indian religions which means attachment, fondness for, devotion to, trust, homage, worship, piety, faith, or love. In Indian religions, it may refer to loving devotion for a personal God (like Krishna or Devi), a formless ultimate reality (like Nirguna Brahman or the Sikh God) or an enlightened being (like a Buddha, a bodhisattva, or a guru). Bhakti is often a deeply emotional devotion based on a relationship between a devotee and the object of devotion. A devotee is a bhakta or bhakt.
One of the earliest appearances of the concept is found in the early Buddhist Theragatha (Verses of the Elders) through the term bhatti. Early texts such as the Shvetashvatara Upanishad and the Bhagavad Gita, describe bhakti as contemplating God as a form of yoga.
