The roots of all beings in Buddhism are determined by karma. Is there a root device that transcends karma, for example, Buddha nature is better than Buddha nature?

The root comes from practice. Some people practice easily in this life because they have practiced in the past. This life is just a rehash of the past, so it's easy. It seems that the root is good. Just like some talented musicians, pianists and writers, they are actually accumulated in the past, and it is difficult to explain without the past. The same is true of practice, and so is the so-called root organ. Buddhism is equal in essence, and karma is equal. Root organs have nothing to do with karma, but they are efforts from generation to generation.
