Desires and Karma

[anagogy]

Are we already experiencing the fourth density? If I will see more and more of the 4th density while I'm alive, I can definitely stay here till my mission/purpose is complete.

Not in my opinion. I mean, our planet *is* developing a fourth density extradimensional physical layer, and we *are* sitting in 4th density space/time, but that doesn't make the 3rd density space/time structures go away (at least, not immediately) -- they are just added to.  And besides, most of us don't have the dual activated bodies that can perceive it, and most of the ones who do have a dual activated body are still predominantly 3rd density activated and only partially 4th density activated (the ratios of activation are not equally distributed). But every coming generation will be a bit more dual activated, so eventually its going to be massively apparent (in couple hundred years). Basically over the next couple hundred years, the human race is going to become naturally, and very obviously, extremely psychic. The reality of life after death will become obvious, as the veil becomes extremely permeable.

We may see some of this play out before our current incarnations are over.
