If you matched up the number of stars ( with telescope) to their astrological 'signs', then you have the three codes that will unlock the entrance. Remember what the journal said? The signs (ex: Leo, Virgo, Pisces, etc.) are in 3 groups and the groups are plainly written in the journal. Forget columns and rows and relationships. That was just an explanation of how Mary grouped them.
Ok? Let us know if you got the codes.
