“I absolutely enjoyed EVERYTHING about the MBSR course. Just right mixture of theory, practice, embodiment exercise. What made the delivery perfect, in my view, was the excellent communication skills (oral, written, body language, tone of voice) or the trainer (Berit). Also the absence of judgement of the trainer.” Cristina

Mindfulness Based Vitality & Ageing (MBVA)

This is an 8 weeks course that was developed and researched by Berit Lewis as part of her Master Thesis on Vitality & Ageing in coorporation with Leiden University and Leyden Academy of Vitality & Ageing.

(…) all the thoughts that sometimes I build up – and sometimes you just go in a circle. So, you can break and step away, that is what I have learnt and that is what I find very useful with mindfulness. My mind gets another set-up. I am stepping out of the circle so I can se everything in a distance.” Quote from a participant in the research rapport

Mindfulness @ work

Mindfulness is an excellent way to improve the work environment and the well-being of the individual employee.

Thriving Life has great experience in offering an adjusted version of the MBSR to organisations in stages. We start with a general introduction and offer all employess the opportunity to sign up to the courses on a voluntary basis. In our experience it creates waves within the organisation. More people sign up and as mindfulness practices and skills spreads into daily life, employees start to respond to challenges and stress with more awareness, calmness and compassion.

Most health care providers are motivated by a deep desire to care for others and often forget to care for themselves. However, if we constantly work ourselves to the limit, we will not have the required energy to help others in the ways we would like to, and our own physical and mental well-being will suffer. Leyden Academy on Vitality and Ageing and Thriving Life are offering an intense mindfulness course over 2 full workdays, with support to establish a regular mindfulness practice in between and after. Participants will leave with skills and knowledge to cope with the demands of their profession.

If you are interested in offering this in your workplace, please send an email to 

“By providing us with a good mix of background information and practical exercises, Berit made us aware of the connection between mind and body. We also appreciated that she showed us how to bring mindfulness into our day-to-day lives. Berit created a safe environment in which people were sharing personal experiences. The course was a success for our organisation. This was a good first dive into the world of mindfulness, and we are planning to continue our relationship with Thriving Life”.

Sleep Well

This is a 4 weeks course teaching you a mindful approach to coping with sleeping-difficulties. Instead of resisting the difficulties, and tossing and turning all night while counting the hours, we work on how to accept and respond to insomnia with compassion. Paradoxically, this approach help us relax and eventually get a better night´s rest.

Learn mindfulness over two full days

Paradoxically the people who wants to do a Mindfulness Based Stress Reduction (MBSR) course are too stressed to find time in their schedule for the standard 8 weeks. We are therefore successfully offering the standard MBSR over two full days (ie. Saturdays) with a month apart and include online guided meditations in between to practice the new skills.

Berit Lewis came to us in UK to deliver a condensed programme for us.  It was a really brilliant experience; superb underpinning theory (the Jon Kabat Zinn MBSR approach along with some ACT), perfectly paced practices and wealth of take away resources to support you own ongoing practice.  Jacqui F
