This weeks Parsha is called Shimos, 'names', and that really highlights the importance of names, particularly the names of tzadikim. From there we can understand a little the supreme importance of the name of the head tzadik, Na Nach Nachma Nachman MeUman.
Rabbainu revealed in Likutay Moharan (A Collection of the Teachings of Rabbi Nachman Vol. 2, Torah 73) That the last letters of the first words of the parsha - ואלה שמות בני ישראל הבאים מצרימה את יעקב איש וביתו [And these are the names of the Children of Israel that are coming to Egypt with Yakov a man and his household] spell out two words: תהלים תשובה - 'psalms' 'repentance'. Rabbi Nachman explains that the names of the twelve tribes - Shivtay Y"H (the tribes of Y"H) - are compromised of 49 letters, which signifies that there 49 gates, and each gate parallels a level of repentance (i.e. drawing close to H"Y). There is a 50th level which is so to speak the repentance of H"Y Himself. Rabbi Nachman revealed that often when people want to repent and draw close to H"Y they do not find their gate, and even if they do find their gate it is locked, and this is the power of the psalms, for King David embedded in his Psalms the key to all 50 gates. So if a person wants to find his gate to repentance and traverse, Psalms are critical.
If we take the first letters of these words (skipping the letter/word 'and') we get: אשביהמאי- this is the acronym of "Yisroel Ber (Saba Yisroel who received the Petek) - Isaac Shlomo (Saba's father) - Esther Mindel (Saba's wife) - Y"H"!!!!
