In Hindu mythology, when the gods and the demons churned the ocean of milk, Lakshmi came out of it holding a garland aptly named Vyjayanthi(meaning a garland of eternal victory). It was her intent to give it to the most eligible being present and Vishnu was right there. Lakshmi garlands him. Hindu mythology and garlands have a lot of synergy. Devotion is usually expressed by presenting the deity with a garland of flowers.
My friend Jaya has started a web site and a service where she can deliver garlands of high quality for expressing your devotion or if you are getting married just as Lakshmi married Vishnu by presenting him with a garland.
