Can meditation stop bad lucks from happening or curse? just curious, do u think chakra would be better?
If your bad luck means, karma ..... no.
Nothing happens by coincidence (luck) there is a cause and effect.
Meditation can overcome curse. However, that is only if you are a very advanced practitioner. Beginners, no.
Disturbance by ghost, Buddhanusati (Reflection on the quality of the Buddha). Loving kindness against black magic (hate).
A curse is a state of mind, not a reality. What you believe you stand a chance of experiencing.
Meditation will help cultivate a healthy mind that would see such issues in their true light, so I guess yes.
