Most Buddhist practitioners will immediately understand and agree with the results of a recent study that shows that people feel better when they tell fewer lies. The study (Telling fewer lies linked to better health and relationships.*) is modest but worth considering.
Notice that the improvements found in the study come from refraining from lying.
“We found that the participants could purposefully and dramatically reduce their everyday lies, and that in turn was associated with significantly improved health,” says lead author Anita Kelly. (Same link as above.)
A good deal of Buddhist practice involves refraining from unwholesome thoughts and behaviors and ultimately eliminating them. Refraining from lying, or “false speech,” is the fourth of the Five Precepts, which are the basis of Buddhist morality. Lies cloud the mind and hinder clear thinking.
