Does one attain peace in dhyãna? Or does it increase the mental strength?
Sri Sri Muralidhara Swamiji
'Shakti' (power) is born out of 'Shãnti' (peace). Our mental strength is wasted due to our skeptical nature, mental contradictions, lustful thoughts and several other mental problems.
When our mind catches hold of a God or a Nãma (Name of the Lord), the mental strength is protected without being wasted.
Therefore, through dhyãna not only 'shãnti' but also great 'shakti' is born.
