A couple of years ago I attended a talk by Rabbi Tatz in which he mentioned the concept of first light versus second light.
He talked about the light on the first day of Creation and then the creation of the sun, moon and stars on the fourth day. He talked about the first tablets given to Moses and the second he had to carve for himself.
The theme being that the first light is stronger and is a gift from G-d. The second light is weaker and one that we have to work for ourselves.
Rabbi Aryeh Kaplan explains the idea further in Inner Space, pp208 note 26.
“The light with which one can see from one end of the universe to the other is also the light that Adam saw in the Garden of Eden and which will be made available to the righteous in the World to Come; Chagigah 12a; Zohar 1:45b, 2:148b; cf. Rashi on Genesis 1:4; Berakhoth 17a; Likutey Halakhoth, Tefilling 5:1”.
By experiencing something the first time without much effort, you can’t then say “I’ll never achieve that” because you have already done it once. Sure the second and further times require a lot more effort but that is the way that the world is structured. Understanding the patterns in Creation is the first step to improving your life and the world around you.
