Saraswati Pooja is celebrated on the 5th day (Panchami Tithi) of the Shukla Paksha of the Hindu month of Magha. This day is also known as Basant Panchami. Goddess Saraswati is worshiped for knowledge, intelligence, culture, wisdom, music and art. It is believed that worshiping Goddess Saraswati in the brilliant fortnight of the month of Magha (fifth day) is of highly importance.
The day of Saraswati Pooja is also called as Abuja Muhurat i.e.; the most favorable Muhurat. Goddess Saraswati is worshiped on Basant Panchami & Sri Panchami, Navratri Saraswati pooja & Diwali Sharda pooja.
Goddess Saraswati is worshiped after Lord Ganesha and installation of Pot (Kalash). Recital of Saraswati Stotra gives more great results. The Dhyan Mantra to worship the Goddess of sagacity, Saraswati, is:
या कुंदेंदु-तुषार-हार-धवला, या शुभ्रा - वस्त्रावृता,
या वीणा - वार - दण्ड - मंडित - करा, या श्वेत - पद्मासना।
या ब्रह्माच्युत - शङ्कर - प्रभृतिभिर्देवै: सदा वन्दित,
सा मां पातु सरस्वती भगवती नि: शेष - जाड्यापहा।।
The above Mantra means the Goddess Saraswati is as the flower of Kund and as bright as white pearl. She is holding the harp (Veena) which increases her beauty as she is sitting on the lotus. Lord Brahma, Vishnu and Shankar worship her for her knowledge and sagacity. We wish and pray that Goddess Saraswati blesses us with knowledge and defend us from the evil.
Goddess Saraswati - one of the trinity of Saraswati, Lakshmi & Parvati. She is supposed to be the wife of Lord Brahma (the creator of universe). Being the partner of Goddess Saraswati, Lord Brahma is also known as Vaagish (Lord of Speech and Sound).
