I'm following the posts at wildmind, and doing the challenge, but I'm slightly discouraged to see the facilitator Bodhipaksa Dharmacari drinks alcohol, and says that the sensation of some parts of the body expanding in size during meditation is an early sign of the Formless Jhanas. hmmm...
I continue to find the challenge useful and interesting, but I sure wouldn't follow the guy as a teacher.
saturated with joy,
you will put an end to suffering and stress.
