1974.11.15 maintaining your third-density existence after the vibration change

[Vestige]

...

We suggest to you, my friends, that you spend no time concerning yourselves with the effort of maintaining your third-density existence after the vibration change to [fourth] density has been completed.

If, within your spirit, your graduation day has come, those things necessary for your emergence into fourth density will be done for you. All will be accomplished by helpers which you must be aware that you have.

It is extremely possible that damage will occur to those things which you identify with yourself in the third density. If we may speak plainly, you will observe the valley of the shadow of death. These very words, my friends, we have spoken to you before and yet you cling to that physical body and those physical surroundings as though your spirit were attached quite permanently.

May we suggest to you that you can find your spirit neither in your head, nor in your hands, nor in your chest, nor in your legs, nor in your feet, that nowhere can you find your spirit; nowhere can you operate to remove it, nor to aid it. Your spirit resides within a shell. The shell may be removed, but that is no matter. The spirit does not perish.

Again to the cycle change. You will be undergoing a journey which is quite unlike journeys from third density to other planes within third density. We believe that those who graduate will thoroughly enjoy this journey.

There will be a great deal to undertake. You may certainly aid those about you in the days to come, my friends, if you will but know in your heart that your spirit is not dependent upon the state of your body, and if you can realize that the valley of death is but a shadow.

If you have confidence in those days, you will shine like a beacon, that you may carry many with you toward their graduation.

What do we make of this suggestion by Hatonn?

Later transcripts indicate that the earth is now receiving fourth-density vibrations.  The fourth-density earth is complete at least in time/space.  It seems the vibrations have indeed changed.  So, what constitutes an effort at maintaining our third-density existence?  On the extreme end, as we might call it, could we or should we give up food, water, and medicines so that our physical body may die and we may pass on to larger life?  Or is this more of a contingent suggestion - that if or when we face disaster and strife (on the level of global upheaval), that we are then to surrender our lifestyle and, when the moment is right, our bodily life?
