I'm presently developing a series of shiurim from Orot haTeshuvah - yes, my initial lishmah read has become a prepare-for-a-shiur read - and I am perpetually stunned by the Torah, beauty, depth, inspiration, confidence and encouragement found in every line.
Here's the sentence I just read (14:36):
כשאדם רוצה להיות דוקא צדיק גמור, קשה לו להיות בעל תשובהWhen a person wants to be a complete tzaddik, it is difficult for him to be a person of teshuvah [return].
Is that not a stunningly gorgeous formulation? Or am I just drunk on Rav Kook, and all of you are wondering what's so special about that sentence?
