Committing Suicide for the Telestial Kingdom
Diary of Charles Lowell Walker

He refered to a saying of Joseph Smith, which he heard him utter (like this) that if the people knew what was behind the veil, they would try by every means to commit suicide that they might get there, but the Lord in his wisdom had implanted fear of death in every person that they might cling to life and thus accomplish the designs of their creator.
