All Phenomena
are just Mental States:
Question:
What is a phenomenon?
Answer:
A phenomenon is an
experienced state manifesting as an appearance,
a mentally
observed event,
a
conscious occasion! Whether experienced as a mental object: Examples:
An experienced thought,
idea, feeling, mood,
or experienced as a physical object: Examples:
An experienced
sight, sound, smell,
taste, or touch: This experience remains just
a mental 'state',
which is what in early Buddhism is
called a discrete 'Dhammā' . This event
is just a passing
moment
of consciousness in time!
As such:
Everything worldly is a mental state!
Nothing whatsoever exists
as
an
independent of
mind 'physical' object 'out there',
until it is observed as a mind experience...
Before and after this direct observation, this 'thing',
remains just an
'idea',
or a mere potential
possibility
of quantum-mechanical likelihood for observation!
Not quite as 'real' anymore...
They once asked the Buddha:
What is the Cause of a Phenomenon?
He replied:
Attention (manasikāra) is the cause of any phenomenon!
Why so? When
attention is present, the phenomenon appears...
When
attention is absent, the phenomenon disappears!
and he further later added:
This World both
Begins and
Ends within
this 2 fathom frame of bones...

The ALL is thereby actually just a
sensed and experienced representation...

Insisting on Direct Experience
as Reality:
This ultra-realistic insistence on direct experience is
also called
Radical Empiricism,
a pragmatic conception of reality, which philosophically was coined by
William James.

The
Phenomenon 'Match' Occurring
only momentarily by
mentally experienced observation! Not 'out there' as an
observer-independent 'substance',
but 'in here' in our observer-mind, as just
yet another experiencable passing mental state...
