In meditation you first get sense control. And yoga will help you with the body and when the mind is steady, concentration will come automatically. When you get such concentration, then you get peace of mind.
Sathya Sai BabaDesire is storm, greed is whirlpool, pride is precipice, attachment is avalanche, ego is volcano. Discard desire and you are liberated.
