A colleague of mine who works in Indo-Tibetan art contacted me for help deciphering some writing on a mural he’s studying. I include here the information and image he provided:

I wonder if I might trouble you to take a look at a detail of mural depicting the learned 17th century Tibetan scholar Taranatha (attached). He is shown holding the stems of two lotuses, one lotus bearing a sword, the other a text, the attributes of Manjushri. The detail I send you is of the text, which I fancy aims at depicting Sanskrit (it is not Tibetan, either cursive or otherwise). Is this pseudo-Sanskrit (on par with pseudo-Kufic), or is it possible that it is indeed readable Sanskrit? Much obliged if you have a moment to glance at it.

I am not able to make sense of the writing, and this is far afield from my areas of expertise. Thanks in advance for any help.
