Where's Heaven?

I've just finished reading "The Courage to Give", a book of inspiring stories of people who triumphed over tragedy to make a difference in the world. The last story, a child's losing battle with a rare and aggressive for of Leukemia shows us how even in death there is life.
Her mother was quoted as saying, "A friend recently described my experience of the past few years as living through a kind of hell. But nothing could be further from the truth. Yes, having to give up a child is pure, searing, indescribable pain that will never go away. But in all honesty, I feel I have been granted a glimpse of heaven, not hell. Thanks to Alana, strangers have reached out to one another, willingly given of their time, energy, and imagination. Inspired by Alana, people from all walks of life reaffirm the best part of their humanity. That's what heaven is: giving of ourselves selflessly and lovingly to anyone in need."
I've gone back and read the last few sentences over and over and find that I've just discovered the true meaning of heaven. Heaven isn't a very distant place.
Heaven is giving of ourselves selflessly and lovingly to anyone in need.
