However, we still need to understand this better: Since Yaakov is the realm of holiness, so automatically all of the Lights Above should flow into him, the levels of Arich Anpin, and Chochmah and Binah etc., so why does he need this “awakening from below” to receive these Lights?
Regarding Eisav, we understand that he needs to do something out of the ordinary to be able to receive Hashem’s encompassing Light, since he doesn’t deserve it. But Yaakov already deserves to receive all the Lights from Above, so why does he need to “prepare delicacies” and other measures in order to receive the blessings from Yitzchok?
The idea is: This blessing from Yitzchok was revealing intense multifaceted Lights from Above the Order of Hishtalshelus (spiritual chain of Worlds), that are incomparably higher than anything already revealed in the Order of Hishtalshelus, as mentioned in the blessing: “An abundance of grain and wine,” which represent dimensions of Torah, Halachos and Agadata, which are invested in material matters, such as Hashem’s attribute of Kindness expressed in the Mitzvah of giving physical crops to the poor etc.
