Excellent Justanordinarytrekker ! you nailed it on those 5 principles.

Summarized things with out compromising the meaning as per Shaolin.

I just want to add few words to your thoughts on

The power of Mindfulness : Word Mindfulness is really an arduous word, we can't explain in words but can experience each and every individual as per their life situation.

In my perspective mindfulness is a satisfaction, mindfulness is an acceptance, mindfulness is an enjoyment,

mindfulness is come out of past, engage with the present moment, no or minimum expectation for future.

Mindfulness is live in present moment and accept your surroundings.

Once again, a fantastic article on an excellent book, accompanied by your superb summary.
