To make the Water of 7 Waters:

1) You collect 7 small bottles of the water from your sacred source and send 6 of the bottles my mail to the each of the other 6 women When they have all 7 (including their own) they blend them
2) You mix together the water from all 6 small bottles you receive, plus your own small bottle from your own sacred source -- and that gives you a large bottle of all 7 waters.
