Moreover, consider that any growth is a sign of spirit. When our hair and fingernails grow, it means that they have spirit; it means that they have force and energy. When we cut grass or clip a leaf from a tree, of course, we will not hear it shout and whimper, and we cannot know whether it felt pain or not, but the fact that they grow clarifies the possession of a spirit. Such sensitivity is not always dependent on a nervous system; sometimes, it is a spiritual factor. Whatever has spirit, has sense.
