After thinking about it, I think it may be a good idea to have a separate post on five hindrances within the new series of posts on “Basic Framework of Buddha Dhamma”
But the main point is that “thina middha” is a hindrance.
– On the other hand, thina and middha are TWO SEPARATE cetasika (mental factors).
– When they appear TOGETHER, that is a hindrance to comprehending Dhamma.
The same is true for uddhacca kukkucca.
I have revised the post, “Key to Calming the Mind – The Five Hindrances” but will provide more details in upcoming posts.
