The Goddess of prosperity, Lakshmi, too became associated with the lamp.There is an interesting legend behind it:
Once Lakshmi was traversing the skies on a dark night when she observed atiny ray of light amidst the ocean of darkness. Curious, she approached itssource and came upon a small lamp burning in a hut and emanating radianceall around. The goddess was extremely pleased to know that the lamp wasthere to propitiate her. She, then and there, bestowed prosperity on theperson who had lit it. Thus developed the icon of Deepa Lakshmi where thegoddess is shown holding a lamp in front of her, the hands cupped in theanjali mudra. The purport being that Lakshmi herself is the light thatdispels away all darkness from our lives. Such a lamp, in addition toserving the ritual needs of a puja, brings auspiciousness and prosperity allaround.
Here in addition to the lamp in her hands, there are twenty smaller lampsset in two layers in the base. Lakshmi herself stands upon an inverted lotuspedestal.
