One group of students listened to a 15-minute LKM audiotape, another listened to a 15-minute CM audiotape, and the control group solved a crossword puzzle. The participants were asked to evaluate their emotional states before and after their given assignments.
Compared to the puzzle group, both meditation groups showed an increase in happiness, a decrease in sadness, and felt more loving and caring toward others. However, LKM was significantly more effective than CM at evoking positive emotions.
“The higher effectiveness of loving-kindness meditation may be a sign that this type of meditation is more suitable to newcomers—those who have never tried meditation before,” study author Ulyana Sirotina said in a news release. “Compassion meditation is traditionally practiced after one has already mastered LKM.”
