...and what else?...well dr von franz in her book entitled 'alchemy' states the following:

There has been an etymological dispute as to whether the word religio comes from religare or religere. Naturally both have the same root - legere, to pick up. Originally it referred to picking up or collecting wood, but legere, to read, has another connection, namely one "picks up" or "gathers together" the individual letters; that is how people read at first and how children still learn.
