Yizkor is a rare opportunity for us to remember those who have passed for the purpose of keeping their memory alive. We are here so we can recall with as much vivid depth as possible those whose lives have touched our own. This act of remembrance renews within us a sense of appreciation and gratitude that our loved ones are not lost to us. Yizkor provides us with an opportunity to say thank you for those who have died. Let us remember, not simply because our memories sustain us, but because  the lives of those who we remember still guide us.
