Shri Lakshmi is the goddess of abundance, beauty, happiness and good fortune. She also blesses devotees with both spiritual and material prosperity, as well as blessing women in matters of progeny.
She is called Vriddhi because she helps in growth; and Matrirupa because she takes care of devotees like a Divine Mother.
As the consort of Vishnu, she is born as his spouse whenever he incarnates. When Vishnu incarnated as Vamana, Parasurama, Rama, Krishna, she appeared as Padma, Dharani, Sita and Rukmini. She is as inseparable from Vishnu as speech from meaning, or knowledge from intellect or good deeds from righteousness.
To pray lovingly to the Goddess of Abundance one may chant the Lakshmi Mantra.
"Om Shreem Kleem Lakshmi Namaha"
