The big challenge for internal work is that you have to do the work yourself. You can get some help in terms of getting advise from friends or going to a therapist to help you process what you're working on, but when it comes down to it, you've got to do the work on your own. No one else can do it for you. That's what I thought as I listened to a friend talk about some issues that she's currently facing. And I also thought about abandonment issues and the times I would tell somebody that I wasn't going away or that I was there for them. No matter how much I might tell a person I wasn't going away, it would never be enough. I could tell that person until I was blue in the face...but if s/he didn't fundamentally believe it on the internal landscape it wouldn't matter.
When you're dealing with an issue, demon, or whatever you want to call it, the solution is found in you and your willingness to face the issue. Other people can provide support, but no one else can provide resolution, because none of those people have the solution. With internal work the necessary focus is on the internal, and finding the solution within, but many times people will try to look outside of themselves for the solution to an internal issue.
In general, when dealing with internal issues I've found a number of methods that are helpful. Pathworking, where you create an internal space to work through issue is one method, while sitting with your issue finding out what the underlying need is, and fulfilling it is another method. For more extreme cases, utilizing the chod ritual can be also be a way to work through issues. What's most important however is that you have the motivation to do the necessary work and follow through on it.
