Even without miracles H"Y provides

Many people say that it is forbidden to rely on miracles, and one must work to earn a livelyhood. The Ramban (Rabbi Nachman...) in this weeks parsha says that is blasphemy, the Ramban says that even through natural means H"Y provides the needs of His creation. For the full quotation see the Hebrew na-nach.net. (It was not surprising to find that on one of the database programs I have, which is very into MSS may H"Y save us from the like, they left out this piece from the Ramban!)
