As this was ‘asked to answer’ from me, I am assuming that you are interested in 21 days online meditation program by Shri Paroksh Yogi Community Uttarakhand (India).
I have not only completed the online meditation program, but I have also attended community’s Himalayan meditation camp in Uttarakhand.
The word ‘challenge’ is no where used in the program, so I have no idea where this came from.
But yes, this is the simplest, effortless and most effective Meditation program I have ever experienced.
This program has 3 steps with each step consisting of 7 days schedule.
1st step consists of Maha Rudra Kriya (MRK) + Effortlessness Guided Meditation.
2nd step consists of MRK + Go deeper Guided Meditation.
3rd step consists of MRK + Completeness guided meditation + Audio Guide on realizing true self.
You can easily find this whole schedule and guided meditations by searching ‘Paroksh Yogi’ online.
My personal recommendation is, do not believe my words of praise for this program, you should try the 1st step yourself which is completely free and then decide whether it connects with your heart or not.
Hopefully, this Meditation program will help you.
