Kanakadhara Stotram is a hymn. It is called Kanakadhara because when Adi Sankara recited it, Goddess Lakshmi created a shower of golden fruit.
Sankara took Sanyasa (renunciation) at the age of eight. Once he went out for begging alms for lunch where he reached a very poor Brahmin lady's house. She had nothing in the house until she found a gooseberry fruit and without any hesitation she offered him. He was moved after seeing the plight of the woman and sang 21 hymns praising Goddess Lakshmi. Goddess Lakskmi appreared in front of him and blessed the poor Brahmin lady with goose berries made of pure gold. The hymn contains a description of the beauty, personality, power and graciousness of Goddess Lakshmi.
