There is no lack of information to consume in this life. The world of entertainment has everything imaginable under the sun to quench any thirst. Pick a platform, a mode, a medium, it will have content from the most vile to the most virtuous at the fingertips of the consumer.
The world of news has pundits from every walk of life and philosophical construct. Academia, law, medicine, finance, defense, politics, education, and on, including their near and distant related disciplines, contains views, positions, and paradigms that have homes for all.
Amidst all of this there must be a “guarding” and “keeping of the heart with all diligence”. There must be a stewardship of the heart. “Out of the heart flow the issues of life.” Keeping the heart is the responsibility of keenly monitoring appetites and what one consumes. It is the intentional effort of determining one’s “yes’s” and “no’s”.
The reason is simple. The heart becomes what it is fed. It reflects what it consumes and like an echo chamber it reverberates what it entertains, watches, listens to, and believes. Thus, we are what we “eat”.
