Spiritual Ability users would have issues with a concept known as "mental roadblocks."

Simply speaking, one's own mentality would cause mental obstacles for cultivation. This might even be dangerous for one's own mind.

Seiji felt that the sudden wave of deep sadness which washed over him must have been a mental roadblock!

He indeed felt somewhat anxious deep inside him. However, suddenly losing control of himself and venting all his emotions like that was a little strange.

Fortunately, he forcefully managed to raise his spirits and get past this roadblock… If he hadn't managed to get past it, he would have doubtlessly become quite depressed—a terrible outcome.
