One can do it when one is exercising or when one is disturbed...
Walk briskly and synchronise the mantra chanting with breathing and walking. It Channelizes the mental energy into productive and higher aspects of ourselves.
Exercise for the day: while acting, make the best choice. When results come let there be choiceless acceptance.
For acting He gave us the intellect to make the best choice and He gave us scriptures for the knowledge to make the best choice and fine-tune the choice-making equipment. He does not interfere in our actions. Like petrol does not interfere in driving. That's driver's choice. So lets study the scriptures and make the best choice.
Since results come by HIS Grace let us accept them as His Prasad. Once we accept the results the mind is calm and we can analyze the results or our actions and make any improvements needed in the future course of action.
