My Saturn is in the 29th Degree of Pisces. I have an astrologer friend who holds that this is a critical position, not because it's bad, but because it has something to do with the galactic alignment (and I hate this because I can't quote chapter and verse and give any more details) - and that gives the position some kind of doorway to the cosmos.
I have not the faintest clue about that theory, myself. I would tend to say that so close to another sign, a planet is beginning to feel the influences of that other - and sort of "rounding off" its business in its current sign. Saturn doesn't move that fast, so that shifting influence - if there is one - is likely to be felt over a long period of time.
Saturn's not that comfortable in Pisces anyway - far too diffuse for its stern influence! It is an orphan there. Coming up to Aries - a sign in which it is in fall - so not going towards great things either. No pun intended - but integrating Saturn in my life has been a bit of a challenge, to say the least. It's more like a hate-hate relationship, as I baulk at any restriction, though intellectually accept there must be some.
Maybe I should go for that cosmic doorway
. I can't think what the Old Man would make of such freedom!
