What Cancer brings to your Mercury

Cancer is a Water, Cardinal sign ruled by Moon. Water is emotional, intuitive and deep-feeling. By mode it initiates. It likes to begin things and set them in motion. So your Mercury, how you think, learn and communicate, takes on that colour: the nurturer: tender, protective and deeply feeling, ruled by memory, home and the tides of emotion.

The sign itself, its dates, element and ruler, has a page of its own: Cancer.

Strengths & the growing edge

At its best, this placement is nurturing, protective and intuitive. That is where your Mercury shines most naturally. Its growing edge is the guarded side. That is not a flaw. It is the place that asks for a little awareness, so the gift does not tip into strain.

A question to sit with

Where in your life does your Mercury most want to be nurturing, and where might its guarded streak be asking you for a little more gentleness?
