Most suffering is pointless, in other words it is involuntary suffering. The function of the human being along the path of mastery is to give purpose to suffering. Suffering is a consequence of having a corporeal body in a finite world and happens through injury and through entropy.

Conscious suffering is not masochistic. Conscious suffering is releasing attachment to suffering and creating energy. Although it seems like a simple enough process it is not. (Due to the complexities of the topic of conscious suffering I choose not to elaborate here.)

All objects/beings produce electromagnetic fields EM or EMFs whether they are biological or non-biological - in short everything. Animal EMFs run at higher frequencies than plant EMFs. All human plant communication occurs through a slower EMF patterning. Some humans (plant or tree whisperers - I suppose. Human egos love titles, BTW) have the patience and training to feel/sense/hear the slower frequencies of trees and other plants. Shared love seems to be the primary emotion of trees and some plants.

If trees and plants are capable of sharing love with humans then they will experience pain as a part of their survival in a finite world of biology.

The majority of current humans are so fragmented they deal in their so-called "rational" or cognitive functions of the prefrontal cortex and are divorced from all else - less conscious emotions and somatic impulses. These tragic creatures are divorced from Earth as a being and as a friend. Its no wonder the current world is such a mess. But it wasn't always this way. Humans were once integrated into Earth's body and soul and could easily communicate and feel what all plants, animals, elements and Earth know and feel / emote.
