The alternating pattern of rising and falling sea level with respect to land is what we know as the tides. What causes this “motion of the ocean”? In one word, gravity. Specifically, the gravitational forces of the Sun and Moon.
The key to understanding how the tides work is understanding the relationship between the motion of our planet and the Moon and Sun. As the Earth spins on its own axis, ocean water is kept at equal levels around the planet by the Earth’s gravity pulling inward and centrifugal force pushing outward.
However, the Moon’s gravitational forces are strong enough to disrupt this balance by accelerating the water towards the Moon. This causes the water to ‘bulge.’ As the Moon orbits our planet and as the Earth rotates, the bulge also moves. The areas of the Earth where the bulging occurs experience high tide, and the other areas are subject to a low tide.

Working with the Moon at certain phases for example, waxing moon is good for working on situations or things that need growth, full moon is good for healing and other matters related to the feminine, waning moon is good for banishing and taking away, while the dark moon is the perfect time for working deeper with the inner self and the mind.
The incoming tide is an auspicious time for bringing matters to a head, attraction and growth and the outgoing tide for taking away or repelling, illnesses, unwanted matters or associations.
