With the Moon in Cancer, you are likely to be influenced by the moods and feelings of those around you, and can be deeply affected by whatever environment you are in. It is very important for those born with the Moon here learn to take responsibility for how sensitive and emotional they are.
Otherwise, you may find yourself constantly tossed around in the sea of life, soaking up other peoples emotional and psychic states with little awareness of what is happening to you and why. For emotional balance, you need to recognize the difference between what is yours and not yours. Taking on the moods of others can distract you from your own best path.
You may be unable to discern between your own feelings, and attitudes, and those of the people around you, for you are extremely impressionable, and likely to be instinctively responding to how others around you feel. This is useful when it comes to nurturing and supporting. The Moon in Cancer gives you an almost psychic sense of what they need and when!
But for your own well-being, it can be problematic if you are constantly invested in others’ needs, with little conscious awareness, of what you need yourself! Ask yourself honestly if you know what your needs are? Can you define them? Do they depend upon the relative stance of other people? Are your true needs being met?
You are advised to take good care of this highly sophisticated emotional mechanism by making sure you stay centered and grounded. This can be achieved in many ways, including spending time alone in nature or by the water when you feel the need. Meditation and retreat will work wonders for you. Learning to invigorate your emotional self will be one of the smartest skills you learn in life. Your instincts are actually your best friend, and will serve you very well once you have learned to decipher between what is yours, and what is not.
You must remember how readily inclined you are to soak up the atmosphere of what is going on around you, and so, stay somehow separated when involved in circumstances where it would be best for you to stay detached. This is difficult, but can be achieved through practice, and using mental imagery to affirm that you are protected and contained. Visualizing a calm and protective white or pale blue bubble around you can be very helpful. The yogic practice of pranayama (controlled breathing) is another excellent tool for keeping your psychic field clear and contained.
