I am careful not to tout the recovery method I teach as a way to help grieving people other than ones self. There's a very specific certification training for people who want to further the work by teaching it themselves. That said, as we deconstruct the myths that are taught about how to handle grief, people inevitably recognize through their own perspective shifts that they are capable of doing better to support others through the process. If that's something you're interested in learning about, I have a great piece written by Megan Divine that I like to refer people to for some ground rules to follow.
*** I do not agree with what I view as Megan's philosophy on grief, which seems to center around grief being permanent based off the things I've read on her facebook page and the suggestion in number 11 that "Grief never really stops". That is, in my experience, not true -- and dismantling that pervasive misconception is the basis of the education I provide. However, the guidelines for the actions that can be helpful for people dealing with a grief process, and more importantly the insights as to what to avoid doing, are pretty good and well explained.
