One increasingly popular form of meditation is loving-kindness meditation (LKM), the practice of wishing oneself and others to be happy, content and at ease. In the yoga tradition, loving-kindness is seen as an opportunity to “cultivate the opposite.”
Where many meditation techniques encourage students to explore difficult feelings or emotions directly, in loving-kindness the invitation is to send well wishes to oneself (who is in distress) as well as the other (who we feel distress toward). This isn’t meant to suppress the feelings as they arise, but instead it can be thought of as a soothing balm, something gently placed on a wound for healing.
Over the past several years, as meditation research has become more prevalent, science has become interested in the effects of loving-kindness practice on the mind and the body. Under the guidance of such well-known contemplatives as the Dalai Lama, researchers believed that LKM would offer similar benefits to other forms of meditation, such as breath meditation or open-awareness meditation.
As it turns out, LKM offers unique benefits that are subtly different from other kinds of meditation. What are those differences? Some just might surprise you.
LKM is a key tool for an optimal life.
One benefit of LKM is that loving-kindness reduces the stress response. Those who practice even a short course of LKM (say over the course of eight weeks) experience less distress than those who do not by the end of those eight weeks, according to this study. Probably no huge surprise there, right?
However, further exploration into this practice may intrigue you. The study on the effect of compassion meditation also investigated the impact of LKM on the body’s inflammatory and neuroendocrine system. At first preliminary results revealed that LKM showed no discernable differences in inflammation compared to the control group.
However, when divided into high-practice group verses low-practice group (i.e., those who practiced LKM each day compared to those with minimal practice) the results became more striking. The high-practice group saw a significant decrease in inflammation compared to the low-practice and no-practice groups. This research highlights two important findings. First, that not only can LKM subjectively reduce distress, but it can impact the body’s physiology as well (in this case, LKM reduced inflammation). The second, equally noteworthy finding is that this only happened for those who activity engaged in the practice of LKM. Simply attending a meditation class once a week was not enough to produce a change. Students had to practice at least a little each day.
Another pivotal study in the investigation of LKM was conducted by positive psychology researcher Barbara Fredrickson. Dr. Fredrickson and her team investigated the impact of LKM not only on emotions, but also on how this practice could actually build personal resources (cognitive, emotional and physical). Her research team invited a group of people to practice LKM over the course of nine weeks. Participants in the LKM group had to practice at least a little every day, and researchers measured subjects on a variety of outcomes — including their experiences of positive emotions, their immunity to illness and their relationships to others. Her question: Could LKM actually build a person’s personal resources?
It did. In their seminal research paper, Dr. Fredrickson and her team write,
The practice of LKM led to shifts in people’s daily experiences of a wide range of positive emotions, including love, joy, gratitude, contentment, hope, pride, interest, amusement and awe. These shifts in positive emotions took time to appear and were not large in magnitude, but over the course of nine weeks, they were linked to increases in a variety of personal resources, including mindful attention, self-acceptance, positive relationships with others and good physical health… They enabled people to become more satisfied with their lives and to experience fewer symptoms of depression.
These findings are powerful.
