At the end of known editions of sefer hatanya, there is a a Luach Rashe Tevot, table of Acronyms. But through the lecture of the book I didn't find the significance of "דש''ע". It's in daf 104b (page 208) in the penultimate line, in the statement:
והוא ירידת האור והשפע דש''ע נהורין שבזוה''ק
I guess that it's obviously not shulchan arurch, nor Shiv'yn because 70 is "ע" and so it have to be "דע' נהורין".
So can someone help me? Perhaps "שבעים עלמין"?
