Friends:

Awareness of Phenomena just as Mental States!

The Blessed Buddha said about Contemplation of Mental Objects:
How does one reflect on Phenomena just as Mental States?

The 5 Hindrances:
One notes & knows when mind is dominated by sense-desire, anger,
lethargy & laziness, restlessness & regret, & doubt and uncertainty!
One notes & knows when mind is released from sense-desire, anger,
lethargy & laziness, restlessness & regret, & doubt and uncertainty!

One understands how there is emergence of sense-desire, anger,
lethargy & laziness, restlessness & regret, & doubt and uncertainty.

One understands how there is overcoming of sense-desire, anger,
lethargy & laziness, restlessness & regret, & doubt and uncertainty.

One understands how there is elimination of sense-desire, anger,
lethargy & laziness, restlessness & regret, & doubt and uncertainty.

The 5 Clusters of Clinging:
One understands such is form, feeling, perception, construction,
and consciousness. One understands such is the causes of origin
of form, feeling, perception, construction, and consciousness.
One understands such is the causes of ceasing of form, feeling,
perception, construction, and consciousness....

The 6 Sense Sources:
One notes & understands such is the eye and the forms and the
consequent obsessive sense-addiction arising dependent on both.
One notes & understands such is the ear and the sounds, the nose
and the smells, the tongue and the flavours, the body and touches,
the mind & the thoughts & the consequent obsessive & compulsive
sense-addiction there arises dependent on both.

The 7 Links to Awakening:

One notes & knows when mind contains awareness, investigation,
energy, joy, tranquillity, concentration and equanimity.

One notes & knows when mind is without awareness, investigation,
energy, joy, tranquillity, concentration and equanimity.

One understands how there is arising of awareness, investigation,
energy, joy, tranquillity, concentration and equanimity.
One understands how there is complete fulfilment of awareness,
investigation, energy, joy, tranquillity, concentration & equanimity.
 

The 4 Noble Truths:

One notes, understands and knows as it actually is:
This is Suffering! This is the Cause of Suffering!
This is the End of Suffering! This is the Way to End Suffering!
 

Thus one lives while considering own internal mental states, or the
external mental states of others, or the mental states of both.
One notices how any new mental state arises, & how it passes away.
Or one is simply aware: There is this mental state now; just enough
for mindful & clear comprehension of the present mental state.
Caused by this acute aware presence and clear comprehension of
any current momentary mental state, one comes to live independent,
unattached, and not clinging to anything in this world whatsoever....
Thus does one dwell immersed in contemplation of the mental states!
