Hi emc:
The order in which we add practices in AYP is not ironclad, though there is a certain logic to it, and the lessons are laid out accordingly.
We don't want "automatic yoga" to be directing our practice routine, for that will certainly be running us willy nilly. Automatic yoga is great, a clear sign of purification and opening going on, but it wants it all right now. Few practitioners can accommodate that without going though extreme discomfort, and ending up traveling slower while recovering from episodes of excess.
On the other hand, if you want to try a minute or two of chin pump between spinal breathing and deep meditation, it will not hurt, and might help quell the random occurrences of it. That way you will be adding some structure, which you can then self-pace for progress with comfort. The rest of the time automatic yoga may be occurring, we can just regard it as "scenery" and easily favor whatever practice or activity we are doing.
Chin pump is good for helping to clear blockages in the throat, heart and front channel, including bringing energy down from the head, which can help relieve pressure in the third eye area. At the same time, chin pump brings energy up through the spine from root to brow, and when ecstatic conductivity (kundalini) is awake the pumping action can be felt through the entire length of the sushumna (spinal nerve), particularly on both ends.
All the best!
The guru is in you.
PS: A light set of asanas before sitting practices can help calm down/smooth out random occurrences of automatic yoga. And, of course, plenty of grounding activity during the day.
