The Fact of No Self Anatta »

The Buddha once epitomized a crucial, yet counter-intuitive fact by saying:
"Sabbe Dhammā Anattā ", which means "All states are without self-&-core!"

This entails a void absence of a stable core remaining as the 'same' in any phenomena:
Internally exists there no "self", "soul", "I", "you" "me", nor any "agent" anywhere in here!
Externally exists there no "substance", "matter", nor any "real world" anywhere out there!
Mentally is there no "controller", "speaker", nor "one-who-experiences" within this mind...
Physically is there no "reality", nor "rock-solid-matter-stuff" outside in that 'world'...

Buddha emphasized that release from this Ego-Substance-Concept was Bliss:
"Blissful is solitude for one who is content, learned and who sees the Dhamma.
More blissful is harmlessness towards all living beings without exception..
Even more blissful is freedom from any craving of sensual urge whatsoever...
Yet, the supreme bliss, is the elimination of this abysmal conceit: 'I Am'...."
Udana – Inspiration: II – 1

Both inner "EGO" and outer "SUBSTANCE" are illusionary ideas!

The Blessed Buddha once said:
In the seen is merely the process of seeing...
In the heard is merely the process of hearing...
In the sensed is merely the process of sensing...
In the thought is merely the process of thinking...
So knowing, you will not be connected 'with that'...
So disconnected you will not be absorbed 'into that'...
So neither with that, nor into that 'You are not' created by that sensation!
When there is no 'You' inferred or conjectured by that very experience,
then 'You' are neither 'here', 'there', 'both', 'beyond' nor 'in between'...!

On realizing the importance of this incident the Blessed One exclaimed:
Where neither solidity, fluidity, heat, nor motion find any footing,
there no sun, moon nor star ever shines. There is neither any light,
nor is there any darkness! When the Noble, through stilling of all construction,
through quieting of all mental formation, directly experiences this,
then is he freed from both form and formlessness,
then is he released from both pleasure and all pain ..."
Udana – Inspiration: I - 10. Further comments and explanation here:

The Buddha insisted on a subtle and profound quasi-pseudo-real world:
"The world is bound up by and shrouded in delusion. It appears as real and
is regarded as if it were fine! The fool bound to his illusive acquisitions,
blinded by darkness, assumes it as eternal, but for one who sees and really
understands, there is nothing real, stable or same, neither here, nor there..."
Udana – Inspiration: VII – 10

"This World both Begins and Ends within this 2 fathom frame of bones..."
SN I 62
"The ALL is thereby actually just a sensed and experienced representation..."
SN IV 15

A crucial core question is: What is actually an experienced phenomenon?
See the equally vital answer here! If mind is directly involved in creating
the very "thing" or "state" it perceives, as an active participatory observer,
then there cannot ever be any "objective observation" or "world out-there",
which is independent of the mind that intends, selects, and manifests it...!
It entails that 'mind' is inseparable from 'matter'. They are Siamese-Twins!
In early Buddhism, the Buddha coined this subtle yet dual Unity: Nāma-Rupa!
Name-&-Form or Naming-&-Forming, since these are dynamic processes, that
in mutual dependence create each other like 2 creepers, that only can grow
up, if growing up twisted and rotated around the other's stem like a DNA-helix.

The anthropic universe develops by conscious selection of many participating
observers. Please note that the U symbolizing the universe gets "fatter" left
by increased observation! American physicist John Archibald Wheeler said:
"No phenomenon is a phenomenon, until it is an Observed Phenomenon...!"
"We are participators in bringing into being, not only the near, but also the
far away both in time and space! Symbolic representation of the Universe is
a self-excited system brought into being by self-reference or auto-creation
by consciously selecting observers over an immensely long period of time...
Such a recursive-reflecting creative concept is similar to the endless series
of receding reflections one sees in a pair of mirrors facing each others....”

“Observations not only disturb, what has to be measured, they produce it!
We compel [the electron] to assume a definite position! We - ourselves -
produce the results of the measurements.” Pascual Jordan quoted by in:
Max Jammer: The Philosophy of Quantum Mechanics, Wiley, 1974 p. 161.

"Fundamental to contemporary Quantum Theory is the notion that there is
no phenomenon until it is observed! This is known as the 'Observer Effect'.
The implications of the 'Observer Effect' are profound because, if true,
it means that before anything can manifest in the physical universe it must
first be observed! This Observer Effect clearly implies that all the physical
Universe is the direct result of consciousness itself!" Alex Paterson.

The stuff of the world is mind-stuff.
(Eddington, The Nature of the Physical World)

The old dualism of mind and matter... seems likely to disappear ...
through substantial matter resolving itself into a creation and
manifestation of the mind.
(Jeans, The Mysterious Universe)

The only acceptable point of view appears to be the one that recognizes
both sides of reality—the quantitative and the qualitative, the physical
and the psychical—as compatible with each other, and can embrace them
simultaneously... (Wolfgang Pauli, Writings on Physics and Philosophy)

The conception of the objective reality of the elementary particles has
thus evaporated not into the cloud of some obscure new reality concept,
but into the transparent clarity of a mathematics that represents no longer
the behaviour of the particle, but rather our knowledge of this behaviour.
(Werner Heisenberg, The Representation of Nature in Contemporary Physics)

This effect is also responsible for the Kammic Reflection of all intention!

HELP! Please Let Me Out of this Empty Illusion!

If you feel slightly weird or dizzy after reading this, you are right on track!
Hihihi ;-) Keep on observing, studying, and reflecting. Never give up Examination!
It is not "reality" itself that seems to be evaporating under your feet, but rather
the unseen, hidden, habitual, and utterly false assumptions you had about it!

"Time and space are not real things out there, but modes in which we perceive!"
