When I was born, I knew nothing of this world. My developing brain contained built-in genetically programmed circuitry tuned to living on this planet with others of my species, and as I experienced the world, this circuitry became activated. I'm talking about circuits like
Broca's area and
Wernicke's area. It's the brain's ability to literally rewire itself at a sub-atomic level growing new neurons and new connections with existing neurons - nanotechnology and quantum physics - that's truly amazing. So my brain also began to grow new, un-pre-programmed circuitry in response to my early environment. As I matured, I chose more and more in what way I wanted my brain to develop. More recently, I am much more explicitly conscious of how I want my brain (substitute mind or soul or spirit if you like) to develop. See my
blog posting below.
That type of description of the brain, in terms of how neurons rewire themselves, completely leaves out what it feels like to be a thinking, feeling human being - the phenomenological experience. Lets go back to the new born again, but approach it from the feeling side rather than the neuron side. Throughout history, people have speculated about the subjective phenomenological experience of the newborn infant. When all its needs are met, the newborn infant appears gentle, peaceful, and happy. When a newborn is hungry, it suffers and we care for it to relieve the suffering. If I try to reach back into my earliest memories, I believe that as a newborn infant, there is nothing in the way of experiencing full on joy, except having basic needs met like food, warmth, being held, and so on. Breast feeding is pleasurable to the newborn, but that's not the same thing as its underlying joy and happiness. And here's where I think we conflate pleasure and joy - we experience pleasure from, say breast feeding, and then the resulting lack of suffering allows us to experience the underlying joy.
As we mature, we learn how to care for ourselves by developing our own brain circuitry to obtain our own food, prepare it, have relationships, earn money, pay taxes, stay healthy, take care of children, and on and on. We become attached to things like good health and money because we spend so much time trying to achieve these things. When we don't have those things, we suffer due to our
attachment to these things. We experience the lack of these things with some combination of fear, stress, sadness, anxiety, depression, and anger.
Then as an adult, we believe that achieving all these goals will restore our underlying joy. Unfortunately I don't think that's the case - all that achieving these things (food, money, etc.) brings us is momentary pleasure when we get what we want, and suffering when we don't. A problem with our culture is that we're focused more on fleeting pleasure than on stable joy, so we tend to ride a roller coaster of pleasure and displeasure, at the whim of our circumstances, and we forget that the pleasure we are seeking is not the same as the joy we were born with.
For some of us, at some point during our darkest hours, we discover that we've lost our joy, and this starts a spiritual quest that results in being "reborn" in the sense that we get in touch with the joy we were born with. This rebirth process requires shedding our attachments to the things we've been pursuing for pleasurable purposes. Once we do that, we can still experience the pleasure of those experiences, but we're not attached to them, so we don't suffer so much when we don't get what we want. "
You can't always get what you wa-ant, and if you try sometime you find you get what you need."
Others of us do not require such a dark journey, and naturally develop the ability to have a deep and joyful life. It seems both paths lead to the same place.
If we're not careful, we can end up where we started after our "re-birth", unless we're practicing appropriate spiritual practices. There are many types of practices that work, but I think they all boil down to one simple underlying practice: Being grateful for each and every day we live, and
loving those around us and lending them our
spiritual eyes.
