I believe Jesus says "where your heart is, there will you be also." So if Jesus says He is God of the living and not the dead, does that mean the love of God is for the living?
Think in terms of psychology. If you are happy, life will appear more positive. If you angry and afraid, then the same reality will look different. We create our own reality often based on our feelings about life. Our feelings can influence our perception.
One classic example is falling in love. When this occurs, the beloved can appear perfect and bigger than life. It can created an exaggerated reality. Your friends and family may not see this, but they may support you, since they wish you to be happy. The emotions triggered by love and infatuation can create beer goggles, that can allows one to see reality through rose colored glasses. It is the same reality as yesterday; science based, but the change of feeling makes one interpret it differently.
Nothing around you needs to change, for one to see life differently, if an internal changes occurs in your brain chemistry. When in the love, the sound of the birds will become beautiful. If you are pissed off, the same sound becomes an annoyance. Reality based on science did not change. Jesus said to be transformed by a renewal of the mind; alter the brain chemistry to that of love; and the your same world will look better and brighter; brain chemistry 1.o.
Much of fake news tries to alter brain chemistry, via inductions of fear and anxiety about all the little things of life, that in the end, never make any difference. However, if you succumb to the induced change of feeling, from rest to fear and anxiety, your whole world will appear to change until the illusions appear real.
Nirvana and Heaven are places one would expect to see when in love. One will not see these places, if one is afraid or angry all the time. It takes work to protect your brain chemistry from outside triggers and remain tin an emotional state of nirvana for the correct perception of reality. In Heaven, there is no longer any work needed to maintain the optimized view. It sticks.
This all has to do with the brain and the creation of memory. When memory is created, aspects in the core off the brain, adds feeling tags to sensory content, when it is written to the cerebral matter. Our memory is part sensory content and part feeling tone. Our strongest memories induce the strongest feelings due to this writing process; marriage, birth of a child, trauma, etc.
In the case of internal and external love or hate inductions, if the brain chemistry is induced to one of these states, the writing process can become biased by that feeling. The same sensory input from external reality, when written to memory, can end up with love or hate tags, based on how the ego perceives reality and then reinforces the underlying feelings. This is part of willpower. It can alter the natural tagging process. The animal will see things as they are in a practical way. The goal in many religions is to maintain a good feeling; love your neighbor, so the writing process does not create a lifetime of bad memories or angry feelings.
Our memory appears to be stored in layers. For example, if we get the feeling of hunger, memories of objects of food appear in the mind. The rest of the memory is not as visible. The feeling of hunger is like a red filter, that overlaps red and blue dots, with only the blue dots visible. The red merge with the filter and appear to disappear. This helps us to focus. Emotional filters can become a detriment to objective reality, since a linear feeling; colored glasses, will only show memories which have the same feeling tag, which reinforces the feeling we have. Conclusions can become biased and reinforced through new memory added to that biased layer. It is easy to get into a loop.
The goals of heaven and nirvana is to find the best feelings; rose colored glasses. Let this positive layer of memory bias your perception, since this will reinforce the best feelings of life, even for bad things, until life is always good; nirvana. It is an advanced application of willpower and choice. This is easier said than done, due to the superego of culture. Both political parties try to induce fear of the other; half the data is suspect. Fake news is mostly about anxiety. Marketing and advertising is about some anxiety and exaggerated feelings of desire. While law is about fear and punishment. None of these things are found in the Nirvana and Heaven layers. However, they can all prevent you from finding that sweet spot.
The alternative is to lower the impact of all emotional triggers, so objective reality is easier to see. The cerebral spinal fluids circulate and will absorb the brain chemicals of emotions. There is a sustain and decay of affect. One needs to be aware of the induction, and try not to reinforce the anger or fear chemicals with will power and loops. I found these negative feelings can also come from the side. The brain will exercise, make use of its entire dynamic range. But all these inductions do not need to be reinforced, beyond the test cycle. Eternal vigilance is the price of liberty.
