HOWEVER, I do believe in positive and negative energy surrounding us has some impact, yet I cannot explain this. (is this what you are talking about, Jen? Is this your form of Law of Attraction? I really did not understand what you were trying to point out).
For me it's a realisation more that we are also made up of these same energies and we influence and build WITH each other eternally, and they don't just flow around us, but also in and within us, through and of us (and everything). The energies are everything, forming, storming, norming (just like group dynamics) but eternally changing 'form'. We are not as solid as we think we are, although we are more dense than some other 'forms' in motion, and less dense than others.
If you take one minute and become absolutely conscious of the gazillion expressions of energy at different calibrations just within one minute, just within your own body (lungs inflating and deflating, heart pumping blood, nerves signalling, muscles contracting and relaxing, expression of excess gas/wind, cells multiplying, etc etc etc - and what most don't realise that whether conscious or not it all is with purpose and with consequence or repercussion as the guy in the nde report uses.
Having done this (and I guess it's part of ET's go within, feel the inner body) then turn to your thoughts and realise - recognise, become conscious that they too are expressions of energy at different calibrations of energy in the absolute love (oneness recognition) to fear (separateness) range of expressions. These are also eternally changing energies feeding into, through us, and everything else and attract at the same calibration of energy - clumping together and forming the repercussions as he uses, 'consequences' as I might use. As I think about it repercussion is probably less emotive.
When we meditate and come to calmness we recognise that we can align with that energy and yes we can use that energy in fear or in love, just as we can any of the energy levels. In energy (spiritual) healing it is the coming into balance with the energies and directing them that influences the area out of balance that creates the 'healing'.
Some recognise this (whether consciously or unconsciously) and learn to harness and adopt various energies - calm or passionate with the same peacefulness of balance and harmony. Being 'in tune', 'at one' etc with 'what is', or 'resisting' etc it' all about energy flow and use.
As you understand it with physical healing, try to also apply it to your thoughts and expressions with feelings. The result, repercussion, consequences are the same. Attracting like energy to the ones in motion and directing it, whether we are conscious of it or not.
The thing with the guy's certainty - that gets me misunderstood at times too. But if you've learned to read the energies and recognise the path and interactions that will feed from and into them, there does become an absoluteness to them. For me I can liken it to music - once you know absolutely what a C chord sounds like, then you absolutely know if what you are hearing (or singing, or playing) is a C chord or a D, or E etc etc The nde experience heightens this awareness of energy to the degree that not only do you recognise the C chord, but you also are intimately aware of the notes that make up the C chord, and the 'consequent or repercussion resonance of different instruments - both group as in a C chord played on guitar as opposed to piano, and going down layers of repercussion to what sort of strings or materials the instrument is employing, even to brands and makers whose contributing energies - love and attention influence the calibre of the notes. My senses are so honed I can pick up that a piano used for recording a song in one decade is the exact same one being played - by a different player - 3 decades later in a soundtrack at the end of a movie (and yes, it freaks me out sometimes when I 'notice'. It might sound absurd to someone when I suddenly go - oh, that's the same piano... etc etc etc but I've 'tested' myself enough times now and confirmed this 'intuition' to trust it.
So it is with resonant energies of thoughts and feelings, although the 'repercussions' may take some time (here) to unfold.
In the light where everything is NOW you absolutely KNOW because its instant and so clear with the absence of the distortion of 'time' and you see it as if it is instantaneous between releasing the thought/emotion/reaction or action and the fruition of the consequences/repercussions. The life review is just this.
Returning to physical/form life with this knowledge, it's like what is in the light is real and instantaneous and so therefore no action/choice is wrong and you can see the multitudes of energies that 'attracted' to each other in order to emerge as the result, whereas here it's slowed down to the inth degree. Add to that the blockages, resistances, denials of the energy as we 'judge' incorrectly through fear brought about by our separation in physical form.
