The sign you are talking about happens one evry 12 years as Jupiter has a 12 year orbit and the same “signs” happen once every twelve years or so. They were talking about this in 2002 and 1990. John was speaking of something different; something truly visionary and symbolic yet spiritually grounded and real at the same time; but not planetary conjunctions and motions. Jupiter takes 12 years to go through all 12 astronomical houses and enters Virgo once every 12 years.
Of course you can ignore the signs. It is up to you to choose.
