Can guided meditation give my friend calm during stress per his chart?

I have a good friend who usually becomes anxious or emotionally overwhelmed whenever life challenges him with problems. He has been considering guided meditation for healing, but he doesn't know if it would actually keep him in remaining grounded during stressful situations. Can his birth chart tell him if guided meditation can give him the calm and emotional stability he requires? Perhaps his Moon or Saturn position indicates that meditation may help him deal with stress more effortlessly and remain peaceful even amidst life's turbulence.
