Sanskrit name (लक्ष्मी) which actually means - "wealth, mammon, happiness".
Lakshmi - is the Hindu goddess of wealth, prosperity (both material and spiritual), light, wisdom, fortune, fertility, generosity and courage; and the embodiment of beauty, grace and charm. Representations of Lakshmi are also found in Jain monuments. Also called Mahalakshmi, she is said to bring good luck, and is believed to protect her devotees from all kinds of misery and money-related sorrows. She is a part of the trinity: Saraswati, Lakshmi and Parvati. All the forms help the trinity of Brahma, Vishnu and Shiva to create the Universe.
Lakshmi in Sanskrit is derived from its elemental form (लक्ष्) lax which actually means - "to perceive or observe". This is synonymous with (लक्ष्य) laksya which actually means - "aim; objective". The Hindu sacred texts, the Vedas call Mahalakshmi as Lakshyayidhi Lakshmihi which actually means she is the one who has the object and aim of uplifting mankind.
Mahalakshmi is called Shri or Thirumagal because she is endowed with six auspicious and divine qualities, or Gunas, and also because she is the source of strength even to Lord Narayana. She is the consort of Vishnu and married Rama (in her incarnation as Sita) and Krishna (as Radha and later Rukmini). All the wives of Krishna were forms of Lakshmi.
In Durga Puja in Bengal, Lakshmi is considered to be a daughter of Durga along with her sister Saraswati and her brothers Ganesha and Karthikeya.
