Rebbe Nachman's Meme

There is an oft quoted line from Rebbe Nachman of Breslov that "The day you were born is the day God decided that the world could not exist without you." Unfortunately, this line does not appear in any of his writings, nor is it attributed to him by any of his disciples. Some suggest it is an oral tradition in his name.
I did discover, however, that Rav Kook says exactly this (עין אי"ה ברכות פרק ב' מ"ו)
The Talmud quotes a prayer (nowadays part of the High Holiday service) "God before I was formed, I was unworthy, now that I have been formed, it is as if I was not formed." Rav Kook writes as follows:
Prior to my formation, since the beginning of time, there was nothing in the world that needed me. If I had been needed to complete any task, I would have been formed. The fact that I was not formed until that time is a sign that until then I was not worthy of being created and there was no need for me until the moment of my creation when the time arrived that I need to do something to complete Existence. If I focus my efforts to the purpose of my creation then I am now worthy. But if my actions are not directed towards good, but to my own selfish desires, then I have not achieved my goal, and I am as unworthy of being as I was previously.

Finding the Wisdom; Connecting to God

The first Torah of Likutei Moharan discusses the value of finding the שכל שבכל דבר, the wisdom in everything. Whatever experiences or challenges come before a person in his life, he should not be satisfied with viewing them superficially, but take the time to look deeper and understand what he is really experiencing. He points out that by doing so, the experience will lead the person to becoming closer to God.

Rabbi Shmuel Moshe Kramer points out that Rabbi Baruch of Mehzboz makes a similar comment on the pasuk מלא הארץ קניניך, which is generally understood to mean that the world is full of God's possessions. R' Boruch explained the verse differently that it is saying that the world is full of methods by which one can acquire God; that there are myriad experiences through which one can develop a relationship with God. Connecting this with the words of the Likutei Moharan, that one should seek to understand every experience in order to find God, we can understand the verse even better.

מה רבו מעשיך ה' כולם בחכמה עשית, How wondrous are your creations God, you made them all with wisdom, i.e. you filled each thing with wisdom through which one can find God, מלאה הארץ קניניך, thereby the world is full of ways to acquire You, full of opportunities to know God and connect to him.
