Sometimes [[Parts]] can form an agenda around healing. ([[If you have an agenda, you're blended with a part]].) I think this may be helpful sometimes, as it can help generate some inertia to do some healing work. However, sometimes parts will form an agenda on wanting to already have been healed already (often so they can stop suffering and get on with their lives), which can lead to bypassing the fears of parts and going too deep, too fast. This can lead to exiling and losing trust with scared parts. It can also lead to severe blending with [[Exiles]].
Severe blending with exiles is painful and I think it can be re-traumatizing instead of healing if there isn't enough [[Self-energy]] present from your own system or from the system of an [[IFS]] practitioner you're working with. And if you become severely overwhelmed by your exile's trauma, [[Firefighters]] can step in to take extreme measures to stop you from feeling. This could include drug use, self-harm, and even suicide.
While maybe slower sometimes, it's safer to get permission from afraid parts, including firefighters, along with getting access to [[Self]], before going deep with an exile. Even if it wasn't safer, I still think we should take our parts seriously, because [[Parts are people]].
Also [[Psychedelics can help parts relax]], but I still think it's safer and more respectful to check in with our parts and get their permission even if they're not very activated while we're under the influence of a psychedelic.
