Table 1. Description of the main practices of the retreat.

Practice	Description	Protocol	Day
Basics of Mindfulness	Practices and insights into mindfulness and acceptance. In this part, explanations are given on how to approach practices during the retreat, and how to deal with distractions, unpleasant bodily experiences, or difficult emotional states.	MBSR / CCT	1
Yoga-Qigong	Simple body exercises to relax tensions, unblock joint patterns, and develop mindfulness in movement. In the case of CTT, references are also made to self-care and self-compassion in movement.	MBSR / CCT	1
Walking meditation	The participant is trained in the ability to be aware while walking. The movement is slower than usual. Breathing and walking movements are integrated. In the MBSR protocol, awareness of the breath and the body is encouraged. In CCT, loving-kindness or compassion is developed while walking.	MBSR / CCT	2
Body Scan	Attention is brought to the various parts of the body. From the soles of the feet to the top of the head. The aim is to develop mindfulness. Every time there is a distraction, the attention is gently taken up again on the sensations of the body.	MBSR	1
Awareness of Breathing	Attention is focused on breathing. Two options are given, depending on the preference of the participants (i.e., focusing attention on the tactile sensations of air in the nostrils or on the sensation of the movement of the abdomen).	MBSR	2
Awareness of Thoughts	It aims to focus attention on the activity of the mind (i.e., on the spontaneous generation of thoughts and emotions).	MBSR	3
Open Monitoring	It is about accounting for the constant flow of subjective phenomena: cognition, perception, and emotion. Rather than choosing an object to focus attention, participants are encouraged to engage in a choiceless awareness in which subjective experience is continuously monitored.	MBSR	3
Loving-kindness and compassion for a loved one	Through visualization exercises of loved ones, practitioners are helped to recognize feelings of love whenever they arise.	CCT	1
Self-Compassion	Practising through assertions generates a feeling of self-acceptance and a desire to overcome suffering.	CCT	2
Loving-kindness for one-self	Meditation practices are aimed at teaching appreciation and gratitude for oneself through visualization and verbalization.	CCT	2
Common humanity	Through visualization practices, a sense of interconnectedness is developed (i.e., the knowledge that experiences of suffering are inherent to all human beings, as well as the pursuit of happiness).	CCT	2
Compassion for others	Through visualizations and verbalizations, it aims to develop compassion for others. Starting with a loved one, continuing with neutral people, and culminating with people with whom one has difficult relationships.	CCT	3
Active compassion practice	A practice known as tonglen in Tibetan Buddhism, it aims to develop a sense of compassion towards others. The participant visualizes how he or she can reduce suffering in other people by doing something beneficial for them.	CCT	3
