Respected Madam,

I am writing this letter to request a leave of absence from my classes on [Date] as I wish to participate in the Dussehra festival celebrations in my hometown, Varanasi.

This festival is of great cultural importance, and I hope attending it will help me understand our traditions. I kindly request your approval for this leave.

                                                         Thanking you,         

    [City]                                                                                          Yours obediently,

    [Date]                                                                                         [Your Name]
