Devotion is defined as loyalty, dedication or love for someone or something. In the context of yoga and Hindu philosophy, devotion is a spiritual path characterized by deep love and commitment often to God, or the higher Self.
In Sanskrit, this devotion is called bhakti. Bhakti yoga is the path of spiritual growth and Self-realization motivated by love and devotion to a specific deity or the Divine within oneself and all creation. This devotion is expressed through chanting mantras, praying, singing hymns and worshiping the Divine.
