What constitutes a ‘difficult' Neptune?  Enough of you have asked, so...  Most astrologers might define this as a square, inconjunction or opposition (90, 150 and 180 degrees) to/from the inner planets, often leading to identity issues/the artist (Sun), neurosis/intuition (Moon), confusion/imagination (Mercury), deception, unconditional love (Venus), quicksand/innovation (Mars), being ‘off planet'/spiritualised (Ascendant), and being rootless/glamourous (Midheaven).  But over thirty years of practice, I've learnt that in every challenge lies the potential to turn it into a skill, and that the positive way of manifesting Neptune in your life is to have a good relationship with the Divine, however you conceive of it as being, whether that be through the universe, creator, God, intuition, angels whatever...  I call it the upstairs department.  It physically manifests instantly in the area between the navel and the solar plexus, it is negated by alcohol and toxins, it is encouraged by water and maintaining psychic space and it is where your dreams and fantasies come become imagined and thus real.  It's where you can dream, and where you can drown.  Time to visit the seaside, methinks.....
