How Unclean Thoughts, Speech & Pornography Bring Depression & Loneliness
Rav Kook deals with the unproductive problem of daydreaming, sexual fantasy and pornography, and how it lowers one into a feeling of depression and loneliness, precisely missing the companionship that a true soul-mate is meant to be. He also deals with the problem of cursing, swearing and unclean speech, and the relationship between our thoughts, speech and actions, whether when used properly or misused. The power of speech is also directly connected with the Land of Israel where Hebrew, prophecy and leprosy for Lashon HaRa are apparent. This helps us understand speech in a modern context.
