Likutei Moharan, Part II 72:12/ליקוטי מוהר"ן·תנינא ע״ב:י״ב

112. The principle which emerges from all that has been mentioned above is that whoever comes to a true tzaddik and hears Torah from his mouth ought to be infused with very great embarrassment and lowliness. This is a sign that he was with a true tzaddik, when embarrassment and lowliness come over him as a result of his having heard some Torah teaching from his mouth. For on account of the Torah which a true tzaddik draws, embarrassment is drawn, as was the case during the Giving of the Torah, as mentioned above.

2And as a result of the embarrassment, which is repentance, the lowliness of Moshe in every single person, within each and every limb, returns to life. Of necessity, each person then genuinely feels his lowliness. However, whoever comes to some false leader and hears Torah from his mouth, and as a result becomes haughty… {the reverse is automatically understood}.

3Nevertheless, we have no idea at all what true lowliness is. For the goal is certainly not to be of low self-esteem, contemptuous and pathetic, someone whom people call “an unfortunate” {in Yiddish, a schlimazel}. For lowliness is the essential life within each and every limb, and it is the entire delight of the World to Come, as mentioned above. And it is certainly not the purpose of the World to Come that one should be contemptuous and pathetic…, God forbid. Therefore, the only thing one has to do is ask God to help him merit genuine humility and lowliness, which is the essence of life and the primary delight of the World to Come, as mentioned above.
