How do you wire a switch / ceiling box from an existing wall outlet?

I have an existing wall outlet that I want to use as my power source to install a switch and ceiling light box. Inside the wall outlet are approx. 4 white wires capped together and approx 2 black wires capped together coming from other existing wall outlets.

    Four white wires individually capped? This is not normal house wiring and I urge you to bring in an electrician. We cannot walk you through this from here because we could end up electrocuting you or burning your house down.

    the white wires are the "common" lines, tying them together is normal.

    Installing a new line for a ceiling light and switch goes well beyond what can be answered here. You should consult an electrician. Tapping into random wires can cause serious problems with other outlets or swiches.

    Consider a pendant light that plugs into an existing wall outlet. You can replace the outlet with one controlled by a wireless battery operated switch that can be placed anywhere in the room.

    In fact, just about any ceilng fixture can be converted to a pendant light. Consult you local hardware store for the ring finial or conversion kit.

    When I saw this post the text was cut off before that.

    I would still say that there is something odd here and would not want to give advice beyond calling in a pro. Black and white wires should be in pairs. There is a bigger picture that I cannot see.
