Based on our Hindu calendar, during the 7th day or the 8th day we perform Saraswathi Pooja. Goddess Saraswathi is the mother of all knowledge, wisdom and learning. She plays the veena instrument. She is a lover of music.
During dasara, on this day, books and instruments are placed before Saraswathi, and we perform pooja to her.
We say the following sloka or prayer to her, and I should mention that this is one of the first payers we learnt in our family, and I guess is being learnt in any Hindu family.
Sidhir bhavathu mey sada
Oh Goddess, Saraswathi, my humble salutations to you, who are the fulfiller of all my wishes. I start my studies with the request that thou will bestow Thy blessings on me.
Here is a link to a picture of Goddess Sarawathi and the sloka as well.
My mom used to make Sweet dosa when we were little. Here is a recipe for the same.
