As for disappearances, contrary to a host of popular channeled information I have recently read, I strongly disagree that anyone is actually going to blink out of this existence and find themselves suddenly and permanently in another — ever! What I do believe is that the planet is going to go through a gradual (yet profound) change in vibration, and as it does, people will either change and go along for the ride, or not. Furthermore, all man-made creations that are not in alignment with this increased vibration of unity consciousness, oneness, and Divine Love, will not be supported by the people (or the planet), and will basically fall away over the course of time in conjunction with the emergence of a new society — a cooperative society that honors all life, and grants equal rights and opportunities to all. By the way, in terms of a time frame, I believe we are looking at years — depending on how quickly (or not) everyone embraces the new vibration — perhaps as many as 15-30 years before the transition to a new society (free of fear, free of oppression, free of tyranny, free of hatred) can be said to be complete (my best intuition-informed guess based on the current vibration).
As for 10-28-11, 11-11-11 and 12-21-12, I feel that these are important milestones that coincide with the end of the Mayan Calendar, the precession of the equinoxes, and unity consciousness. That said, I am looking forward to giving my energy and attention to several different group meditations that are scheduled to take place during this period as I truly do feel that these events affect change in positive ways, however, as per the guidance of my guides and angels, I won’t be expecting anything in return. i.e. no personal breakthroughs, no outcomes of historic significance. (Truth be told, my guides have consistently recommended that I do my best to live without expectations, period, regardless of the situation or the particulars.)
