Saraswati (Sanskrit: सरस्वती, IAST: Sarasvatī) is the Hindu goddess of knowledge, music, art, speech, wisdom, and learning. She is one of the Tridevi, along with the goddesses Lakshmi and Parvati. The earliest known mention of Saraswati as a goddess is in the Rigveda. She has remained significant as a goddess from the Vedic period through the modern period of Hindu traditions. She is generally shown to have four arms, holding a book, a rosary, a water pot, and a musical instrument called the veena. Each of these items have a symbolic meaning in Hinduism.
