The body soul relationship.

We should never say that our bodies are not important, only our soul is important. Rabbi Shimshon Pinchas gives that mashal of a large office building that has millions of dollars of equipment in it but one fuse in the basement breaks and all of the equipment is worthless. This is the relationship between the body and the soul, the body is our connection to this world and has to be taken care of.
from a Shiur by Rabbi Efraim Wachsman
