Lakshmi is the Goddess of Prosperity and wife of Lord Vishnu, mother of Kama. The other names of Lakshmi are
Haripriya - the beloved of Hari;
Padma - the Lotus;
Padmalaya - she who dwells on a lotus;
Jaladhija - the Ocean born;
Lokamata - the mother of the world.
She is believed to have sprung from the froth of the milk ocean when it was churned by the Devas and Asuras, in full beauty with a lotus in her hand. In the descents of Vishnu, she was his associate. When Vishnu was born as a dwarf, she appeared from a lotus as Padma (Kamala), when he was born as Rama (Parasu) she was Dharini; when he was Raghava (Ramachandra) she was Sita; when he was Krishna, she was Rukmini.
When Vishnu takes a celestial form, she appears as divine; if he is a mortal she becomes a mortal too, transforming her own person agreeably to whatever character it pleases Vishnu to assume.
"Om Sri Maha Lakshmyai Namah"
