The most important gift you can give to a bereaved person is your presence. Whether it is sitting by their side as they cry, offering words of care, taking out the trash, or distracting them when they request it, having someone to lean on is the best gift of all.
If you are looking for practical ways to help your grieving friend, I highly recommend Anne-Marie Lockmyer's book When Their World Stops: The Essential Guide to TRULY Helping Anyone In Grief.
And if you also want to give them a gift that supports them through their grief process, here are few suggestions available from the Mindfulness & Grief Institute:
The Mindfulness & Grief Book
