The latest Tanya lecture explores the mystical dimensions of prophecy as described in the Holy Epistle. It discusses the limitations of Moses' spiritual apprehension, explaining that he could only perceive the external aspects of the highest Divine attributes, while the inner essence remained beyond his reach. The teaching draws on Kabbalistic concepts, illustrating how Divine wisdom is filtered through various spiritual levels before becoming accessible in the world, particularly through the Torah. The lesson highlights the distinction between the inner and outer dimensions of Divinity and how these are reflected in prophetic vision and sacred texts.
