I NEED MY SPACE

U93 Crash debris site, Shanksville, PA, 9-11-2001

"My definition of a sacred space is a very simple one. Any place that's capable of being defiled is by definition sacred." Edward Linenthal, historian and religion scholar, from our book, Life of Meaning, speaks to the issues of our memorializing the places where unspeakable human tragedies have occurred. Gettysburg, Pearl Harbor, Oklahoma City, World Trade Center and Shanksville, PA (crash of airliner U93) have all become part of our American psyche as sacred space.
Linenthal speaks of a narrative we form to immediately begin the memorializing process after a tragedy. "Yes it was horrible but...the people came together...the heroes responded...we will rebuild."
He states that while we "fixate" on the coming together aspect of the tragedy it also contributes to tearing us apart. This is illustrated most by deciding how to appropriately memorialize the space involved in the tragedy for the whole community.  How should it be done?
The indignities of closure. He also has less than kind words for the grief speak that is used in the aftermath, such as: "Closure" or "Healing Process." Linenthal refers to these as "pop" psychology statements. Rather he says that the healing process is what Oklahoma bombing mourners refer to as :the "new normal." The old life is no longer. It's the new life and the impact of the event that is the reality. He refers to this as rebirth and creativity. This can lead to what Linenthal calls "active grief."
Do you agree with Linethal's assessment of the grief process? 
Is it similar or different from the classic Kubler-Ross model of the five stages of grief or Teresa of Avila's "Interior Castle,"  the seven stages of development leading to union with God?
What is active grief anyway? How can we become active in our grief?

How can it be a memorial to great tragedy in our world?
