to Gathering the Dew
The man and the woman are symbolic for the two aspects in the Great Work; male/female, the fixed and the volatile. The gathered dew is used for distillation, and thus goes through the process of being fixed and being volatile. This is symbolic for your consciousness going through the process of refining your inner energies.
The ram and the bull, being the first signs of the Zodiac signify the this is the beginning of the Great Work.
