Demonic power causes you to think of retreating.

　　All of you should realize that cultivating the spiritual path is not an easy matter. If you decide to cultivate, then demons will come around. They will not come from only one direction, they will come from all directions at once. There are demons of sickness, demons of vexation, demons in the heavens, human demons, and also demonic ghosts. There are demonesses as well. Demons appear, from places that you do not expect, to disturb you so that your resolve will waver and your cultivation will falter. They use many tricks to seduce and tempt you. They also threaten you, trying to get you to retreat in fear. They hope your samadhi power will vanish and your resolve for the spiritual path will disappear.
