11 days


In this 11 day Sadhana we will focus on your kidneys and adrenals to recharge your batteries, fight fatigue and help you diminish the negative side effects of stress. The daily guidance emails will support you in finding your way to flow with live instead of going against the current.


Everyday you will do the Kriya for the Kidneys & Adrenals to beat fatigue and stress. When the kidney energy is strong we are able to flow along with life without fear & worry.

Hi there, I wanted to say that I really liked the kriya, my kidneys liked it. I feel that it has done them well. I sometimes wake up at night having pain in the kidneys. I hope that doesn‘t occur any more when I‘m doing this kriya once in a while. I really liked your support and it helped me to start with the kriya every day! Thank You! -- Kat

After practicing Hatha Yoga for 10 years I switched to Kundalini in 2011 and I am teaching on a daily basis ever since. My classes always are a deepening experience beyond the comfort zone, to discover new dimensions of ‘being’. Self ­observation is playing a key role throughout the practice towards self­ discovery. Teaching Kundalini Yoga is the love of my life and I am passionate about sharing this sacred technology to inspire people on their spiritual journey. Out of this passion Tim and I founded the online Kundalini Yoga School in 2016.



As a Yoga-psychologist I integrate the teachings of Kundalini Yoga with Psychology. An early fascination for the mind made me choose to study Psychology at the University of Amsterdam. I love sharing yoga via the Online Kundalini Yoga School. Besides Kundalini Yoga classes and private consultations with individuals, I also lead journeys & retreats at inspiring locations worldwide. I am grateful guiding students to establish themselves in their hearts, towards a life filled with compassion and kindness.

Is this guided Sadhana going to be a live-stream?

In this Sadhana we work with 1 pre-recorded kriya video on the  Video Page. It is not a live-stream. This will allow you to play the kriya video at a time that suits you best.

Will I receive a different video every day?

We will practice the same meditation with 1 pre-recorded kriya video on the Video Page. This will allow you to play the meditation-video at a time that suits you best.

At what time will I receive the daily guidance email?

We send out the emails in the early morning (your timezone). This will allow you to read it before you start your practice.

Do I need to do this Sadhana at 5 a.m. in the morning?

You don't have to get up at 5 a.m. in the morning. You can do your practice anytime of the day. Choose a time that works best for you. It is recommended to meditate before sunrise, because at that time the energy is most neutral for meditation and yoga.

Do I need previous experience with (Kundalini) Yoga to join this Sadhana?

Previous yoga-experience is not required for this meditation. Your motivation and commitment to the practice is enough.

How much time do I need to carve out for this practice?

For this Kundalini Yoga Kriya 'for the Kidneys & Adrenals' you will need around 45 - 60 minutes each day; including a relaxation afterwards. The assignments and reflections via email will take about 5 - 10 minutes each day.
