Is Knowledge some kind of evolved mental process?

It’s not a mental process, it is the process of concentration. Also, evolution means to be reborn, to come out. See, we are already spiritual beings, the spiritual entity is already inside us. We have to evolve in order to really taste it. It’s like having food ready, but you have to go inside the dining room in order to taste it. Then your understanding will be a balanced understanding. It is called the middle path. The will then has a spiritual inclination. Or you can call it a spiritual baptism. These are all different words, but they mean the same thing. www.manavdharam.org
