This is not to say that the modern era is likely to dish up quick-fix remedies to psychological challenges faced by mankind. We've an uphill climb against the determination of power to be absolute, in the process corrupting itself absolutely. We have to contend with physical, mental and chemical warfare and be prepared to accept that things are not likely to get much better any time soon. But what we can do, with what we have at our disposal, is to accept the changes in our own thinking and actively cultivate those doing us most good, while guarding against those that do us most harm.
There is no teacher more commanding than experience, and we never forget the lessons directly learned in this way while we may forget the entire contents of a book, or all the writings on the blackboard (I'm old enough to remember those!) at school. We experience quantum effects throughout our lives, and the more credence we give them, the more capability we have to utilise the gifts therein.
We can change our worlds simply by appreciating the two principles above, and if you then add wave-particle duality to consider that you only exist in particle format for a Planck time (if that) before your wave packet collapses into the next version of yourself, it makes absolute sense to abandon past-future anxiety and adopt the premise that the new You is in constant upgrade of manufacture. We are responsible for our quality control.
Ego is powerful stuff, whatever it may turn out to be, and while it has a place in the games we play it makes no difference what we think of ourselves in relation to others, we're clearly all in this together. Perhaps we have hit a turning point where we need to 'switch on' in quantum terms, so that we become accustomed to these laws being at work in our lives, and take account of the fact that it's up to us how we think, so that we can feel what we want to feel, which in itself would satisfy a clear need for compassion when it comes to the welfare of the planet - the planet of which we are part.
