Loving-kindness meditation (Metta): cultivating inner warmth
You may have worked on your concentration, your breath, your observation of thoughts. And yet, in your inner dialogue, you remain your harshest critic. Metta meditation addresses that dimension — warmth toward yourself and toward others — which is rarely spontaneous but trains like a muscle.
You may have worked on your concentration, your breath, your observation of thoughts. And yet, in your inner dialogue, you remain your harshest critic.
Meditative practice from the Theravada Buddhist tradition consisting of actively cultivating kindness by repeating intention phrases ("may you be safe, may you be happy, may you be at peace") toward oneself, loved ones, neutral persons, difficult persons, and finally all beings. A large meta-analysis (Zeng et al., Frontiers in Psychology, 2015) showed its efficacy in increasing positive emotions.
Why kindness trains like concentration
Kindness is not a fixed personality trait — it is a trainable capacity. As you can train concentration by repeating returns to the breath, you can train warmth toward yourself by repeating intention phrases. After 4-6 weeks of regular practice, the inner dialogue shifts.
Our inner dialogue is in most cases harsher than what we would say to a loved one in the same situation. Clinical psychology research (Kristin Neff, University of Texas, on self-compassion) shows that this self-harshness correlates with more anxiety, more depression and less motivation — not the opposite as the popular belief would suggest.
Brain imaging (Klimecki et al., Cerebral Cortex, 2014) shows that Metta training progressively activates areas associated with affiliation and care (anterior cingulate cortex, insula) and reduces amygdala activity (alarm). In practice: after a few weeks, you react less hot-headed to setbacks and criticism.
Nala’s 3 Metta sessions
Maya guides 3 progressive Metta sessions. You can do them in order, or pick the one that matches today’s need.
1. Kindness toward yourself (15 min, Maya). The hardest for many. We start with self because it is the foundation: if you cannot direct kindness to yourself, you cannot truly offer it to others. The phrases ("may I be safe, may I be happy, may I be at peace") are first repeated slowly, then Maya invites you to feel their effect without forcing.
2. Kindness toward a loved one and a neutral person (18 min, Maya). The practice then extends: first toward a dear person (easy), then toward a neutral person (the neighbour, the cashier at the supermarket). This extension trains the capacity to feel kindness independently of spontaneous affect.
3. Universal kindness (22 min, Maya). The complete practice. Includes a difficult person (without becoming heroic — we choose someone annoying, not the longtime enemy), then opens to all beings. This session is longer and generally reserved for those who have already done the previous two.

Who Metta is particularly useful for
Metta is particularly beneficial if:
- You are your own harshest critic (perfectionism, recurring self-judgement)
- You are going through a period of anger or resentment that does not pass (post-breakup, chronic family conflict)
- You have done a lot of "technical" meditation (concentration, body scan) and feel the warmth dimension is missing
- You work in a helping profession (health, social, teaching) and feel empathy fatigue ("compassion fatigue")
Metta is less indicated as a first response if you are in acute crisis (major anxiety, panic). In that case, see the SOS and breathing exercises first to stabilise, then return to Metta in a calmer state.
Integrating Metta into a routine
A simple answer: do one of the three sessions once or twice per week, alternating with other meditations. Metta is not meant to replace mindfulness meditation — it complements it. Many experienced practitioners alternate: 4-5 days of regular meditation, 2-3 days of Metta.
Complement with: meditation for anxiety (often tied to self-criticism), quick meditations (for daily moments), and the 8-week MBSR mindfulness program for beginners.
