We live in a dimension of duality. Everything has its opposite. You cannot have death without birth, and you cannot have birth without death. When we die to our physical bodies we are born into spirit, and when we're born into bodies we are experiencing a death from spiritual. It's a matter of perspective, but you can't have one without other.
Birth is generally considered a joyful event. Since every death is also a birth there should be some joy in death, too, no? And since every birth is also a death, births can be painful and fearful, too. Birth can actually be more of a traumatic event than death. Imagine dying to your life in spiritual then entering a helpless little body and shooting out of birth canal. And then you're stuck in that little helpless body and all your memory is gone.
Dying in spiritual dimensions is similar to dying in physical. First, you lose your body then you go through some kind of tunnel-like thing, and then voila! you're in a different dimension. Death and birth are same thing! They are very same thing!
Death and birth are two sides of very same coin. This polarity is ubiquitous in our reality. Birth/death is going on all time. The person we were five minutes ago is already dead. They no longer exist! Every single minute of every day we are dying and being born. We birth a new self with each passing minute. All we have to do is look to nature to see endless birth/death cycles. We cannot birth something unless we die to something. Death is important.
It is human tendency, however, to think of phsyical deaths of our bodies when we think about death. This brings up fear, so we start trying to mentally block out death. We no longer see importance of and beauty of death in its integral part of ongoing life. When we shift our focus away from death, we no longer give it energy it needs and what happens is we stop birthing as much. Any diminishment in our level of dying leads to a diminishment of birthing. For instance, in order to birth new ideas, we must let some old ideas die.
Birth/death, birth/death, birth/death. They go together. If you try to do without one, then eventually you start doing without other.
So let's change focus and talk about joys of death excluding death of physical body. Let's talk about joys of death that happen on a daily basis; little deaths that happen continually. How many times do you die on a daily basis?
What about anger? Say you hold a lot of anger for a particular person. Can you die to that anger? Would that be a good thing? What birth would occur simultaneous with that death?
