Obama said his meetings with family members were filled with memories of brothers, sons and daughters who had left their mark on others.
Describing the recovery of some victims, he said this reminds one that even in the darkest of days, life continues and people are strong and people bounce back and people are resilient.
"Out of this darkness a brighter day is going to come," he said.
This was Obama's first public appearance after the Friday's tragic incident in which a lone gunman went on a rampage in a theater in Aurora in Colorado, following which the president had given a pause to his reelection campaign.
Accused James Holmes, a postgraduate student who police say bought guns and stockpiled 6,000 rounds of ammunition in the months leading up to the gun attack, is currently being held in the jail adjacent to the court.
