Tuning the 7 Main Strings
We start from the main string most further away from the tuning pegs, so if the sitar's string side is facing you, the 1st string would be the right most string.
1st String - Ma - F (An octave below Middle-C)
2nd String - Sa - C (An octave below Middle-C, below the F of 1st String)
3rd String - Pa - G (below the C of 2nd String)
4th String - Sa - C (Two octaves below Middle-C, below the G of 3rd String)
5th String - Pa - G (one octave above the 3rd string, above the F of the 1st String)
6th String - Sa - C (Middle C, above the G of the 5th String)
7th String - Sa - C (one octave above Middle C, above the C of the 6th String)
