What
is simple & straight, yet also very intricate?

Once
the Blessed
Buddha said this:
This Noble Truth of
Suffering has been made known by me;
This Noble Truth on
The Cause of Suffering has been made known by me;
This Noble Truth on
The End of Suffering has been made known by me;
This Noble Truth on
The Way to End Suffering has been made known by me!
Within these
4 Noble
Truths there are innumerable meanings & implications,
a myriad of shades & nuances and countless aspects, features and details...
Therefore, Bhikkhu, an effort
should be made much of to understand:
All this
is Suffering;
an effort should be made much
of to
comprehend:
Craving is the Cause of Suffering!
An
effort should be made so to
realize:
No Craving is the End of Suffering! An effort
should be made to penetrate,
remember, and develop:
This Noble 8-fold Way which ceases all Suffering...
