Anything that can become the object of attention dissolves under that attention. This is because reality is in the seeing and not it the seen, the seen being only momentary under such attention. So if you can bring everything that in any sense belongs to you into the field of attention it will melt away, and this can be taken to express its inherently empty nature, but might just as well be seen as an artifact of attention. The entire process can be made even more respectable by being expressed in the language of awareness which brings with it a subtle blurring of the distinction between subject and object. None of this necessarily involves a dissolution of boundaries. A different sense of the notion of inherent nature might be the possession of a boundary, the boundary being over-determined by various largely unconscious conditions. In this understanding there is no dissolution of the object but only of the boundaries; things don't vanish into thin air but are subsumed into a larger whole. This is a stronger sense of emptiness or better of non-duality, but when the boundaries are dissolved then everything that was being kept out by the boundaries is now allowed in and you must be capable of withstanding the inrush from the space of all possible experience.
