“when Lubavitchers say “tzaddik”that are usually referring to tzaddik as is defined by Tanya.”
You mean in terms of צדיק גמור” vs בינוני..
Now, is there a difference between a צדיק and ‘צדיק גמור’ in terms of the Tanya as well….
Meaning, based on the Tanya’s level of Tzadik (i.e. לבי חלל בקרבי) is there a possibility of any level of “completeness” above צדיק to צדיק גמור?
