Jai Sri Ganesha,
Peace of mind is the prime subject for man unto the truth of being man,
There is no specific discipline and Yoga to train the mind to resort to peace,
Yet a man may culture it with the truth of goodness through the magnetic flux of respective souls,
The first milestone is to prevent self from fault-finding in others and the concluding milestone is to introspect self-time and again, gradually mind reach at the horizon of peace,
May Lord bless all,
Thanks please
