What is Feeding  the Investigation of States Link to Awakening!

The Blessed Buddha once said:
Bhikkhus, just as this body, is sustained by feeding, exists in dependence on feeding
and cannot survive without food, exactly & even so are the Seven Links to Awakening
also sustained by feeding, they can also only exist in dependence on feeding and they
cannot survive without feeding... And what, bhikkhus, is the feeding of the emergence
of any yet unarisen Investigation of states Link to Awakening and feeding of the very
completion by advance of any already arisen Investigation of states Link to Awakening?
There are states that are:

Advantageous or Disadvantageous.

Blameable or Blameless.

Ordinary or Excellent.

On the Bright or the Dark side.

Frequently giving careful and rational attention to them, is feeding the arising of any
unarisen Link to Investigation of states Link to Awakening and feeding the gradual
fulfilment of any already arisen Investigation of states Link to Awakening...

And what, Bhikkhus, is the starving that obstructs the emergence of any yet unarisen
Investigation of states Link to Awakening & which also hinders any already arisen
Investigation of states Link from reaching any fulfilment by deliberate development?
There are, bhikkhus, things that are Advantageous or Disadvantageous, Blameable or
Blameless, Ordinary or Excellent and on the Bright or the Dark side: not giving frequent,
careful & rational attention to them; not considering them much & often; is the starving
that prevents any unarisen Investigation of states Link to Awakening from arising and
also blocks any already arisen Investigation of states Link to Awakening from reaching
complete fulfilment by mental development...

Comments from the classical commentaries:
Examining is the characteristic of the Investigation of states Link to Awakening
(Dhamma-Vicaya-sambojjhanga). Scrutiny, inspection, inquiry, exploration, analysis,
research & repeated review is the purpose of the Investigation of states quality.
Interested and eager curiosity is the manifestation of this Investigating function.
Before, while and after doing any mental, verbal or bodily action simply ask yourself:

Are this behaviour really: Advantageous or disadvantageous, blameable or blameless, ...

on the Bright or Dark side and act accordingly! Keep on refining this discrimination!!!

 

Conditions helpful for the emergence of the Investigation Link to Awakening are:

1: Asking Questions.
2: Clean, healthy & hygienic mental & physical praxis.

3: Avoidance of people with small & unclear understanding.
4: Friendship with people with exact & profound understanding.
5: Repeated reviewing reflection on all deeper questions.
6: Commitment to finding out precisely why & how...

There is investigation of external states and there is Investigation of internal states.
Both is a crucial for all progress towards understanding. Awakening is pure Knowing!
