The 4 Steps to Spiritual Force:
The Blessed Buddha once said:
Bhikkhus, these four Steps to Force, when developed and
cultivated,
are Noble and releasing, since they lead the one, who acts upon them
out of this world by the complete & final destruction of Suffering...
They lead to disgusted disillusion, to detachment, to ceasing, to peace,
to direct knowledge, to
Enlightenment, to Nibbāna. What 4?
Here, friends, a Bhikkhu develops and refines:
1: The Steps to Force of concentrated
desire
created by effort...
2: The Steps to Force of concentrated
energy
created by effort...
3: The Steps to Force of concentrated
thinking
created by effort...
4: The Steps to Force of concentrated
investigation
created by effort...
These four Steps to Force are Noble and releasing,
since they lead
anyone, who acts upon them out of this world by the irreversible
destruction of Suffering... The lead to utter disgust, to disillusion,
to detachment, to ceasing, to direct knowledge, to Peace...
They lead to Enlightenment, they lead to
Nibbāna...
