What is my meditation truly healing inside me, is it my mind, or is it something written in my stars?

Name: Komal Date of Birth: 27th August 1994 Place of Birth: Bhopal Situation: Meditation gives me peace, but only for a short time. I keep wondering if something else is influencing me. Could planetary changes be disrupting my life? Can you suggest mantras or remedies that reduce this mental strain?
