The Holy One said to Abram, “Go forth from your native land, the place of your birth, and from your parent’s house to the land that I will show you.

לך לך "Go forth from" (literally, go for thyself) — for your own benefit, for your own good: there I will make of you a great nation whilst here you will not merit the privilege of having children (Rosh Hashanah 16b). Furthermore, I shall make known your character throughout the world (Midrash Tanchuma, Lech Lecha 3)

Or one can say "go for yourself" - it seems to me [we can understand this] through the way of a hint: a person needs to research, and search, and seek, always in order to see the greatness of God in every thing that their eyes see, and through this they will merit that the Holy Blessed One will give them intelligence and understanding to succeed and comprehend the upper worlds. And the way to reach this level of being able to observe the greatness of God is to fix one's traits first and foremost, since the Exalted Holy Blessed Name created the human with all sorts of traits, and each and every single trait has a side and a piece that is towards holiness, and also towards the opposite, God forbid, as known. And a person needs to break into their choice so as to use their traits only to holiness, and then they will merit to understand and observe the greatness of God. And the Exalted Holy Blessed Name opens for that person the springs of wisdom, to conceive and comprehend in every instance with the one's higher understanding, more and more, what one's mind eyes have never seen.
