Reincarnation? Options

Can anyone give me some good arguments for Reincarnation?

I have myself quarreled inside when it comes to this topic.
I prefer however to keep disciplins apart and keep the Relegio/Mystical to it self and not blend in natural science.

Scientifically the most importand factor defining life is procreation.

Since most of my spirtual work has been Hermetic and Kabbalistic i tend to see thing through those traditions.

The "wheel" of rebirth, or Samsara of the Hindus does not really have an equivalent in either Kabbala or Hermetisism even if the "climbing" towards the light of anihilation, Nirvana does (in the case of Kabbala it would be Kether).

I HAVE however speculated in the sphere of Yesod, working as a final matrix for creation might harbour som "stuff" or "memories", patterns of the created on the way up after death and that energy of a sort corresponding might "grab" it in going down to be created.

This could explain being reborn as severel different people as one Dalai Lama was.

This is not well thought through Kabbala or canonic in anyway though.
My main concern is the here and now.

Sometimes rather naive arguments like "the little flowers returning in spring" are used. Thing is, its not the same flowers. They procreated and rotted.

One theory I have toyed with is the idea that we are reincarnated through our DNA. I mean what is DNA? Its the chemical make up of evolutionary memory. Like binary code in software programs, the human genome diffines the peramaters of our perceptive existance. So maybe in our lives the things we experience are imprinted on our DNA then passed on to future generations. If "spirit" is an energy that makes us living and not dead than soul for individual only lives, at least on the mundane level, until the point of death. But if DNA is the capacitor for spirit than the human spirit as it uniquely experiences life from one person to the next is what is actually reincarnated through the ages. Therefore past life experiences are not actually a person reliving what they themselves once lived, but remembering what someone else, apart of a shared human spirit, once lived.

Personally I think more or less reincarnation is a possibility but I don't think we really understand exactly what it means to be reincarnated.
