According to Buddhism, at the moment of conception, when your father's sperm meets your mother's egg, a biological process is ignited. But this isn’t merely physical. It is where the karmic stream re-links with a new biological form. You are in the samsaric trap caught in vijñāna, 0/1, dyadic consciousness. The ālaya-vijñāna, the storehouse of rebirth potentiality, is on the verge of collapsing. The collapsing soon begins, the immeasurable into measure, forming—gestating:
—The polarity of left/right
—The heartbeat: lub/dub
—The neural network: on/off
—The genetic code: adenine/thymine, cytosine/guanine—a 4-base binary system
—At the arising of vijñāna, then nāma-rūpa, then the six sense spheres
The wonder of wonders, you are about to be reborn again. Hopefully, you will have a good rebirth and be a strong, healthy baby. Hopefully you will have a great mom and dad who will introduce you to the dharma. If not you've got another lifetime to work your karma out.
