Feeding the Serenity of Equanimity!

The Blessed Buddha once said:
Bhikkhus, just as this body, is sustained by feeding, exists in dependence on
feeding
and cannot survive without food, so are the
7 Links to Awakening
also sustained by feeding, they can also only exist in dependence on feeding
and
they
cannot remain without feeding... And what, bhikkhus, is the feeding
of the emergence
of any yet unarisen equanimity
and also feeding of the
completion
by condensation of any arisen Equanimity?
There are states that are basis & source for Equanimity! Frequently
pointing
careful and rational attention to them, is feeding the emergence of unarisen
equanimity & also feeding of the gradual fulfillment of any arisen
Equanimity
Link to Awakening... And what, Bhikkhus, is the starving that obstructs
all
emergence of
a yet unarisen equanimity, and
which also hinders any already
arisen
Equanimity Link from reaching complete
fulfillment by development?
There are states that are the basis and source for the
equanimity!
Not giving frequent,
careful and rational attention to them; not considering
them much
and often; is the starving that prevents an unarisen
equanimity
from
arising and also blocks any already arisen equanimity from reaching
any complete
fulfillment through training in the form of frequent meditation!
Comments:
The main basis and source of Equanimity is knowing, seeing & understanding:
All beings are born, created, conditioned and shaped by their past kamma...
They are owner, debtor, inheritor of the effects of their prior behaviour.
Whatever they do - good as bad - only they will feel the long-term results!

Comments from the classical commentaries:
Imperturbable onlooking ballance is characteristic of the
equanimity.
(Upekkhā-Sambojjhanga). Moderation, seeking a
neutral middle, composure
and
control is
the purpose of the quality of
Equanimity
(Upekkhā)...
Imperturbability is the manifestation
of the equanimity. This stable
yet still
plastic patience purifies all the other
advantageous mental states, which thus
reach their maximum, when joined with
Equanimity...

Further conditions helpful for the emergence
of the equanimity are:
1: Impartiality regarding all living and sentient
beings...
2:
Indifference regarding all inanimate material constructions...
3: Avoiding biased people, who prefer
favouritism and one-sided partiality...
4: Friendship with well ballanced people unmoved by both pleasure
and pain...
5: Commitment to ballance the mind into even and imperturbable Equanimity!

There is Equanimity
towards living beings and regarding material things!
There is Equanimity towards internal states
and regarding external states!
There is Equanimity
towards all past, present, and future times
and events!
There is Equanimity towards all mentality
and regarding all
materiality!
