Some teachings from Acariya Mun
Here Ãcariya Mun contrasts relative, conventional reality (sammuti) with Absolute Freedom (vimutti). The citta, the mind』s essential knowing nature, has been dominated by fundamental ignorance (avijjã) since time immemorial. This fundamental ignorance has created within the citta a center or focal point of the knower. The existence of that false center engenders an individual perspective which is the nucleus of selfidentity.
This "self" forms perceptions of duality (the knower and the known) and from there awareness flows out to produce the world of the 5 khandhas and of all sensory experience, which in turn reinforce the knower』s sense of individuality. It all begins with the currents of the citta, which flow out to create the entire sensory world, the world of conditioned phenomena. Because of this, it is said that all physical and mental phenomena are relative, conventional realities (sammuti). They exist only relative to the knower, the one who perceives them. As such they are merely conventions that the citta has brought into being and given a subjective identity to in order to experience its own manifestations. In turn, these manifestations become incorporated into the citta』s sense of its own identity. Thus the known becomes indistinguishable from the knower, and duality comes full circle, trapping the citta in a web of self-delusion. The citta is reduced to depending on its manifestations to assess the nature of its own existence.
When fundamental ignorance has been destroyed, the focal point of the knower disintegrates, which causes the "self" perspective to disappear from the citta altogether. With the disappearance of self-identity, all manifestations of the citta, all relative, conventional realities, are divested of their power to deceive and no longer appear within the citta. Although they do continue to play a role, in the form of the 5 khandhas, as long as the Arahant remains alive, they are no longer incorporated into the citta』s identity and have no part in conditioning its outlook. This is called vimutti – absolute freedom from all conditions. No conditions whatsoever exist for this freedom.
