THANK YOU :)

This course pushed me to make myself happy but when I approached in the middle of the course, one happy person is the sole factor to make his/her community a happier place to live. This course is powerful and the technique is novel and sublime.

I understood that it takes time and effort to unlearn my learned behaviors. Through this subtraction method, I will practice self-reflective meditation to see a new myself. Thanks for introducing this method with real chats and examples.

Reflecting on my past opened my eyes that my worries are from the false pictures I have taken.

with the subtracting method, I can proudly say I am becoming happier each and everyday of my life.

Thanks for creating this wonderful course.

es un gran curso, todos deberían tomarlo, hubiera querido que en mi sistema educativo se implementara, siento que hubiera alcanzado un gran potencial en ese momento, pero mi momento es ahora, un gran aprendizaje te deja este curso.

I am very pleased I did this course. I have enhanced my knowledge and understanding of both my inner self and the people and circumstances around me. I am also very grateful to Professor Duck Joo Lee for sharing his wisdom.

I learned how delusion and false pictures in our minds blocks the reality of our current situation. False world inside us makes harder to see clear the present moment. The principle to live happily is to live in present.

Excellent course. Takes you step by step to subtract worries or events that remain in your mind. These memories make you look at the world in a false perspective. Helps you to be happy and focus on your goals in life.

Dock Joo Lee is not only a good professor but an incredible human being and he really knows how transmit the world of meditation.

This course helped me a lot eliminating the things that were blocking my life. Thank you.

I did like the course and found it helpful. Though for me it was a bit of a beginner course. i also had a problem with understanding when Dr Lee had guests on and they were talking in another language. Hard to follow.

Great course, Dr. Lee makes it enjoyable, relatable, easy to understand and the method he teaches is practical and friendly to apply in everyday life. It changes the way you understand the world and yourself.

I highly recommend this course to anyone who is constantly overwhelmed by the never-ending flow of his/her thoughts and who is having hard times moving forward because of any reasons coming from the past.

I learned so much about myself through this course, and will continue to practice and apply meditation and self reflection, even that part was an eye opener for me, on my road to happiness and completion

Thank you for your lecture. it was so amazing moment in my life. now i can realize my life better than before. it was not difficult. it was only me who make myself tough. thank you so much.

This course was very informative and has convinced me that meditation is part of a healthy and meaningful life! Thank you Professor Duck Joo Lee for teaching us the subtraction method.

THIS WAS ABSOLUTELY THE BEST COURSE I HAVE EVER TAKEN. I TRULY ENJOYED MR. LEE. THIS WAS VERY HELPFUL FOR ME. I WILL CONTINUE TO PRACTICE EVERYDAY. THANK YOU, DEBORAH HOWARD.
