Friends:

 

Venerable Sariputta explains the Seven Links to Awakening!

 

Venerable Sariputta once said: Friends!
Friend; the Bhikkhus replied. Venerable Sariputta then explained this:
Friends, there are these Seven Links to Awakening. What seven?

1: The Awareness Link to Awakening: sati-sambojjhanga.

2: The Investigation Link to Awakening: dhammavicaya-sambojjhanga.

3: The Energy Link to Awakening: viriya-sambojjhanga.

4: The Joy Link to Awakening: pīti-sambojjhanga.

5: The Tranquillity Link to Awakening: passaddhi-sambojjhanga.

6: The Concentration Link to Awakening: samādhi-sambojjhanga.

7: The Equanimity Link to Awakening: upekkhā-sambojjhanga.

These are the Seven Links to Awakening.
In whichever of these Seven Links to Awakening,  I wish to dwell in the morning,
in that I abide in the morning; in whichever I wish to dwell at noon, in that I abide
at noon; in whichever I wish to dwell in the evening, in that I abide in the evening...
Suppose a king or a minister had a cupboard full of clothes of many various colours,
then whichever pair of clothes he wished to put on in the morning, that he would put
on in the morning; whichever clothes he wished to put on at noon, that he would put
on at noon; & whichever clothes he wished to put on in the evening, that he would put
on in the evening: so too, in whichever of these Seven Links to Awakening, I wish to
abide in for whatever period, in that indeed I easily abide dwelling fully absorbed...

If it occurs to me that now there is The Awareness Link to Awakening present in me,
then it occurs to me that it is measureless, & it occurs to me that it is well established;
and while it is remaining I know that it remains; and if it falls away in me, then I know
that it falls away caused by this or that specific condition & definable circumstance!

So too with the other six links to awakening. I note & know their presence & ceasing.
