What our clients and students say?

I find the readings accurate and they give me useful guidance each month and for the year. I feel grounded. For example, I was planning a relocation of countries and was able to get clear information on times and direction of travel. I also got guidance on most appropriate kinds of work to do. This stuff works though–if we let it. I’ve been able to direct decisions at times when life has seemed very complex. That has been supportive and helpful. Thank you.”
G.R., London, the United Kingdom
“I’m doing 9 Star Ki sessions with Alex for years now. It explains the tendencies of the energies of the universe, the planet, and my own. What I like about it is that it never tells you not to do something; it might tell you how to prepare or what to be aware of. Very useful for traveling, healing, business… also I really appreciate Alex’s availability if I have a question in between sessions.”
—Gubi Koltz, Luxembourg
I am pleasantly surprised by the course. The method of uncovering basic features of a person was unknown to me. However, I very quickly understood why I did not understand people that are close to me. This can be regained by the simple teaching that 9 Star Ki provides. Thank you, Danka.”
Dana Vesela, the Czech Republic
"Danka’s course revealed a lot to me. I perceive my loved ones from a different perspective now, as I can read their character from their numbers and how they can act in certain situations. Of course, also myself. I like that we learned everything in the course gradually and step by step, we received materials to print and assignments. And last but not least, I also like the support during the course. Danka took great care of us, answered our questions and organized joint online meetings. Highly recommended.
Veronika Hladisova, the Czech Republic
“The reading you did for me last year was amazingly accurate and helpful. Thank you so much! I look forward to getting this year’s reading from you soon!”
P.L., Connecticut, USA
“I used so much information in this course for a better and deeper understanding of myself and others. It was very enriching for me and showed me a view of people from a different angle. I recommend it to everyone who is on the path of self-discovery and getting to know others.”
Kristyna Anna Gladis, the Czech Republic
“I realized that we are a combination of many qualities that are given and we can take a closer look at them, how some mutually support each other, while others not at all 🙂 When we realize the pitfalls of our relationships, we can continue to consciously work with them. Oh, and the fact that my younger son is constantly drawing wiring and plugging in electricity to all the games is written in his numbers, I fell on my ass! :-)”
Marketa Sobotkova, the Czech Republic
“Thanks to 9 Star Ki, I know how I function in peaceful and stressful situations, how I affect those around me, and I can find out all these about all my loved ones or new acquaintances, as well. The course is great for anyone who is interested in self-knowledge and who wants to know how best to treat others and what to expect from them.
Jarka Novakova, the Czech Republic
