Why does my mind wander every time I meditate—could my moon sign be the reason I can’t stay still?

Name: Jivika Date of Birth: 12th June 1996 Place of Birth: Hyderabad Time of Birth: 3:40 AM Whenever I sit to meditate, my thoughts keep wandering. I feel there might be a planetary reason for this. Should I chant mantras related to my planets to calm my mind?
