You can use your Astral Temple before you do the dedication ritual i.e. make one and do the dedication ritual in there, and usually that means you/someone wouldn't have done much or any meditating at all yet. If you are not able to do the dedication ritual with tools, in your bedroom at home, in a park where it is safe and private, etc., then you can do it in your Astral Temple and wait until you are able to do it fully.
When I was "backsliding" from christianity, I just said a single prayer to Satan about something, and now I'm here. I did the dedication ritual fully a bit later. Satan knows I was contacting him, before I did the dedication ritual fully, and he knows that it's not always easy to be yourself and do things in some situations, so you can do the dedication ritual in your Astral Temple when you are ready, then do it fully later when you are able to.
