Purification of the Mind is obtained through worship of Lakshmi Devi. Contrary to popular belief, Mother Laxmi is worshipped not for material wealth, but for good and noble values (spiritual wealth).
More important than material wealth is the inner wealth of spiritual values such as love, kindness, sincerity, self-control, self-discipline, etc. By the practice of such spiritual values in our daily lives, our minds become purified.
The lotus on which the Goddess is seated symbolizes the Supreme Goal of Self -Realization.
