"See I set before thee" - "רְאֵה, אָנֹכִי נֹתֵן לִפְנֵיכֶם" (Deuteronomy 11:26)
The reason that this Parshah is read before Rosh Chodesh Elul is because the month of Elul hints to thought, because the world was created in Tishrei. In truth, the entire concept of the creation of the world was from the goodly thoughts that were essentially from the side of goodness. It is well known that the main thing that a person is judged for on Rosh Hashanah is thought, therefore it is a mitzvah to think good thoughts, as has been explained elsewhere, and a person must love his friends, and want to do good for them. This is why before Rosh Chodesh ELUL - אלול - which is "Ani L'dodi V'dodi Li" - "אֲנִי לְדוֹדִי וְדוֹדִי לִי" - "I am my beloved's and my beloved is mine" (Song of Songs 6:3), we preceed with "See I...", that as much as a person looks into the "I", with any blemish, thus do "I give before you", and with this thought should one "serve the LORD with joy" - "עִבְדוּ אֶת ה' בְּשִׂמְחָה" (Psalms 100:2).

"And you should not consume the soul with the flesh" - " וְלֹא-תֹאכַל הַנֶּפֶשׁ, עִם-הַבָּשָׂר" (Deuteronomy 12:23)
This means that you should not destroy your soul with the flesh, for sometimes a person might, God forbid, damage his soul with the flesh, inasmuch as he eats meat only to fulfill the desires of his yetzer hara. Therefore, the Torah says not to destroy his soul by eating meat when it is only for the sake of a desire and not for the sake of a mitzvah.

"Do not cook a kid in its mother's milk" - "לֹא-תְבַשֵּׁל גְּדִי, בַּחֲלֵב אִמּוֹ" (Deuteronomy 14:21)
The reason for the prohibition of cooking meat with milk, which comes from this verse "do not cook a kid", is to hint that this is the holiness of the Jewish people. Through this do you become "a holy people to the LORD your God" (ibid.), that a person should know that he does not have any life force whatsoever from the ways of nature. Rather "and all the souls (or all that have breath) praise the LORD" - "כֹּל הַנְּשָׁמָה, תְּהַלֵּל קָהּ" (Psalm 150:6), as the Sages teach that this means that we should "praise God with each and every breath we take" (Midrash Rabbah: Genesis Rabbah 14:1). This is hinted to by "do not cook a kid in his mother's milk", that one should not mix the power of today with the power of yesterday. For it is known that the root of a person's strength is from his mother's milk, which was the first material that sustained him in his lifetime. The Torah says we should not mix this life force with the future, meaning that we should realize that every second is a brand new gift from God and the automatic result of the previous second. This is why the verse uses the term "cook", which is a process that is contingent upon time. Rather a person must believe that each and every second is a brand new life force sent from God, and if your remember this you will become a "holy people unto the LORD your God".
