Do you remember the quotes below? Try to find them in the book:

Man exists physically for the sole purpose of developing spiritually...
It’s the destruction of your entire planet that is at risk - with no second chance if you don’t place your trust in those who want to help you. (this is a 1987 warning)
... sometimes a planet will DISAPPEAR in a solar system...
At the moment, (on Earth) most responsibility is taken for the physical body, but this is a serious mistake...
If you make a mistake, you pay the penalty - immediately, in ten years time, or in ten centuries time, but errors must be paid for
To impose one’s will on another, in a way which deprives the individual of the privilege of exercising his own free will, is one of the greatest crimes that man can commit.
People… don't care what might happen to your planet in the years to come. They selfishly chase their gains, expecting to die before "whatever is going to happen" happens.
If the Earth DISAPPEARS, as a result of horrific cataclysms, they assume they will already be dead.
There, they are making a big mistake...
...your physical body will wear out and die one
day, whereas your psyche, being part of your Astral body, never dies...
...we have our roles to perform, as does every creature existing in the universe;
in fact, everything, including a single pebble, has its role
… telepathy is not hindered by language barriers.
… Drugs… not only do they ruin physical health,
they also reverse the individual’s process of universal evolution
Faith is nothing in comparison with knowledge.
… if you want to ‘elevate’ yourself, you must meditate and then concentrate, which is different,
although often the two are confused
… the more you cultivate your mind, the less you will be burdened by your physical body
It is the reading of Auras that counts, .. not the perceiving … them
When you push away your neighbors, your son or your daughter - if you aren’t always ready to help even those whom you don’t like, you contribute to the disintegration of your civilization
Do you see how history is just a perpetual recommencement?
Thoughtlessness and irresponsibility are not qualities of civilized nations
.. one must not rely on perception.
We continue to be nourished without overloading our stomachs. This also allows our minds to remain clear and alert .. after all, our minds must be a priority….
What counts most is not appearances, but what is behind them...
… you are on your planet in order to learn how to live, suffer and die, but also to develop spiritually as much as you can.
The reading of the Aura in order to heal the physical body is nothing compared with what such a reading can achieve for the psychic body, or the physiological body
…whole life will have been preoccupied with purely material concerns, with insufficient time allowed for matters of the spirit
… now, on Earth, you have returned to a point that is worse than that of 2000 years ago...
At certain times during sleep, your Higher-self is able to call your Astral body to itself ...
… it is essential your sleep is undisturbed by intrusive noise or by nightmares resulting from harmful impressions received during the day
If they could see the damage that is caused, they would vacate the discotheque quicker than if there was a fire …
Technology should assist spiritual development, not confine people, more and more, within a materialistic world, as is happening now on your planet.
…from time to time we are permitted, or even advised, to offer a helping hand but we are formally forbidden to ‘serve the meal on a plate’ …
It is in the area of the psyche that, on Earth, your greatest problems exist.
… the universe is a gigantic atom and everything is affected by that.
…the priests took pains to ensure that the people were kept in ignorance to the greatest extent possible. By lowering their intellectual and physical level of development over the course of years, the priests were better able to maintain domination over them…
…man’s principal obligation, regardless of which planet he happens to inhabit, is to develop his spirituality.
You should always bear in mind this main point: An Astral body, in all cases, must conform to Universal Law, and, by following nature as closely as possible, it can achieve the ultimate goal by the fastest path.
A certain percentage of these people are arriving at a very critical point in history and we feel that the time has come to try to assist them. If they will listen, we can ensure that they take the right path.
… The human body … is surrounded both by an Aura and by an etheric force (field) of oval shape…
Don’t confuse logic with the illogical distortions of religions.
You know that, when you want to explain something that is not a material fact, even to your closest friends, you are confronted by skepticism …
You have but a few years left in which to arrest the pollution before the situation becomes irreversible…
… the source of the coming disasters is the pollution which is growing daily on your planet, and its consequences will be felt very soon - much sooner than you can imagine…
… materialism poses one of the greatest threats to your present life and your future lives
