This weeks Parsha (Torah portion) begins with blessing to those who keep the Torah. The first words are: If in my commandments you go - אם בחקותי תלכו, taking out the middle word - which represents the Torah, we have the words: if you go, which have (without the last letter) the gematria (numerical value) of 491 = Na Nach Nachma Nachman MeUman. This signifies that Na Nach is the "Derech Eretz" - proper conduct, which preempts and surrounds the Torah.
Rash"i explains that going in the Torah means: שתהיו עמלים בתורה, to toil in the Torah. Rabbainu said that to be a Jew, i.e. to constantly rise from level to level, one must be in the Holy Land of Israel. Rabbainu also explains how to rise from level to level in Likutay Moharan (Tora 31). There are two parts to the Tora, revealed - doing, and hidden - listening, the hidden part being an aspect of prayer. One must take his studies to a place of prayer until what was considered hidden and esoteric to him will have transformed to be revealed and subject to be acted upon. Then he will be confronted with even more esoteric and hidden boundaries to constitute his prayers.
The word עמל - toil, alludes to this process of ascension. The first letter ע, means eye, to see and understand. The next letter n, stands for מלכות, kingdom - the female sfira which is an aspect of prayer. The final letter ל - למד, means to learn. Thus the word hints to this process of seeing to make ones learning into prayer, so that one's prayers can be then realized and acted upon, thus being afforded higher aspirations and prayers.
Thus the first verse of the parsha ends: ועשיתם אותם, "and do them". The final 4 letters - מאתם have the gematria of נ נח נחמ נחמן מאומן, and the verse is saying that with this holy way of Nanach, ועשיתם אות ם, you will make the letter ם, that is you will make what was esoteric and hidden - the aspect of ם, into ועשית - that wich is revealed and doable.
Great blessings of Na Nach Nachma Nachman MeUman!
