In contrast, in the spiritual world, the preceding one is higher. The son is a result of actions of his father, but in a worse state, in a more coarse desire. Thus, Isaac is a lower state than Abraham, and Jacob is lower than Isaac.
On the other hand, the deeper and stronger desire, the more opportunities it has to be corrected in similarity to the Creator. Therefore, from the point of view of the generations’ development, every new generation is worse than the previous one. However, from the standpoint of using the level of desire, every following generation rises higher, i.e., it attains greater Light.
Therefore, something that was impossible to do for Abraham, due to his small depth of desire, is manifested in Isaac, in his left, egoistic line. This work does not belong to Abraham. He only has to “tie,” to limit his awakening egoistic desire. Whereas, Jacob connects with both forces and begins to realize himself. As a result, a soul begins its development and it consists of two properties.
