Implementing Emptiness Practically What is the manner in which those meditating on emptiness actually bring their contemplations into a practical, experienced form? In other words, how does insight (on emptiness) become effective in every day life?
Your question is a good one. If I understand it correctly you are referring to the process of "bridging" your experiences in seated meditation into the time between such meditation sessions. You recognize that there is such thing as focusing one's meditation in a certain way (on emptiness) and it's not clear how to bring that focus to one's daily activities. If that isn't your question I apologize. If that is what you are asking then it's important to understand some of the practical aspects of focusing on emptiness. Focusing on emptiness is not necessarily the same as meditating on emptiness nor is it the same as realizing emptiness. 

Focusing on emptiness is using the idea of emptiness as taught by the Buddha to change the way you see your self and your life.

Focusing on emptiness can be described as keeping impermanence always in mind. In other words, whatever you see/hear/taste/smell/feel/think ALONG WITH the organs you use in order to see/hear/taste/smell/feel/think are going to die (or end) REAL SOON! That type of reflection has the PRACTICAL effect of doing two things. First, it causes an increase in awareness of the precious little time we have in this body. And second, it creates an ambivalence towards things that waste that time. 

In other words, when you come into awareness of death you start to realize the futility of grabbing onto things you experience with the senses and you also realize the limitations of those organs you are using to perceive objects. This creates dispassion and eventually revulsion for these habits of grabbing onto such ephemeral, unrewarding objects. The nature of all objects of the senses is to burn unto death (as taught in the Fire Sermon [SN 35] among many other sutras). When you meditate on emptiness you are focusing on that truth within all objects of your life and all aspects of what you call your "self" (those organs of perception).

You don't actually need to "sit" for meditation to "meditate" on emptiness in the way I am describing. "Sitting" actually makes it easier to see into this component of fire/death within all objects and without sitting, perceiving objects of everyday life in this way takes even more courage, determination, persistence and most of all, faith in the dharma (+the Buddha &amp; the Sangha). But even if you sit and experience the jnana states sequentially the meditation on emptiness must continue in the same way at each new state. Even the jnana of "nothingness" (one of the highest states experienced by the body) must be seen with using this meditation on emptiness; that is, 'this state is temporary, it too shall pass, it too is on fire.' That is why Sariputta would describe his experience of the jnanas as (forgive my paraphrasing): 'And then the first jnana assailed me, and then the second jnana assailed me . . .' etc! [I will look for the reference to this sutra and add it later, it's in the SN]. The mind as an organ of perception is on fire/subject to death/empty and so, the appropriate practical response to the experiences it delivers is the same: dispassion, revulsion &amp; eventually release.
