Elders' Teaching on the Spiritual Sickness of Jealousy and Gossip

Elders have told me that impact of backbiting and gossiping, fueled by jealousy, destroys the Soul and lasts more than two lifetimes. It would be better for someone's soul, in a way, to just physically kill them. Just an example of the profound level of spiritual sickness and darkness at the heart of Jealousy, backbiting and gossip! What a very pitiful spiritual disease. If someone does this to us all we can do is pray for them or we will become just as spiritually sick as they are and maybe more!
