Tanya Chapter 2 part 4. Do parents get to choose their child's soul?

Now we comprehend how cleaving to Torah scholars is akin to attaching to the Shechina. By connecting with holy people who represent the level of the “brain,” we can experience and manifest G-dliness. But what about those who rebel against Torah scholars and defy them? Are they still connected? Yes, they are, but their spiritual nourishment originates from an external space, lacking intimacy and vitality.Another crucial aspect to consider is the influence of parents on the child’s soul. The Zohar teaches us that the holiness of parents during conception significantly impacts the spiritual quality of their child’s soul. However, the Zohar speaks not of the soul itself but rather of its “garment”—the medium through which it manifests and expresses its essence. The refinement level of this “garment,” whether pure or coarse, greatly influences the soul’s ability to express itself and receive divine influence. Nonetheless, the essence of the soul remains independent of parental influence. Sometimes, a sublime and lofty soul is born to parents of lowly or sinful character.
