Namaste.
There are many spontaneous hand mudras that happen as a direct result of awakening the Shakti and I have even gone as far as exploring the Bharata Natyam (Classical Indian dance) to try and find out if there were any actual corresponding names for them...but no luck.
I have found a picture of the one that gives me the
most comfort, but it doesn't have a name:

Even the sheer act of placing the fingertips together (another thing I regularly do to feel my heartbeat and slow it down) doesn't even have a term for it among the mudras:

Even the "Church and Steeple" mudra (which also happens) I cannot find in the list of Mudras anywhere:

These are just a few of the hand mudras that I regularly do (or rather occur by themselves) that aren't even on the list!
Suffice to say, I just gave up looking and trying to find a correlation, because it just 'feels good'
anyway.
Aum Namah Shivaya
