Its a symbol the late Dr. B. N. Pandit would put on all his publications.  I was given the information off-list that it is a Trika based symbol invented by his teacher, who would write under the name of  Amṛtavāgbhāva.

Can you share more details such as where you found it, what made you consider that to be a yantra etc. ?
