In my opinion the answer is no. Spirits demons ancients whatever you refer to them as, guide you in your ascension. They help you to help yourself getting to that point when you are ready. They cannot ascend you. This is your internal process only.
Emergency purposes is a very vague description.
The world has been in chaos “for the lack of a better term because I don’t like that word” for centuries that, I consider an emergency, there should be more ascended masters walking the face of the earth if that was the case. I just feel that the needs of the planet and the human race as a whole would far outweigh any one individual’s immediate need to become ascended.
But if anybody finds that immediate shortcut, please send me a PM LOL
