Neptune in Pisces forms a supportive sextile to Mercury in Capricorn
This is an excellent day to dream and communicate your desires to the Universe. With what medium you choose to do so is up to you. For example you can write down a list of wishes you'd like to materialize and say it out loud, or if drawing is your cup of tea make a painting of your dreams and hopes. You choose what suits you as long as you connect. Neptune is the boundless planet that connects to other realms and in flowing contact to Mercury the messenger we can ask the messenger to forward our wish to Neptune. Other days Neptune and Mercury might not be friends since one is the ruler of logic and the other of all non- logic :) so take the chance...
You can also ask for guidance in any question or concern that might occupy you mind.
In Mythology which Astrology uses to explain the energy of the planets Mercury is connected to Hermes, the winged God which actually had his wings placed on his feet. Neptune was the ruler of the seas and therefore the unconscious and all things intangible but not less real for that...
