There is much maritime lore about the seventh wave, particularly about it being the largest wave in a group, and the one that hits the shore directly. The next time you find yourself by a body of water, watch the waves as they come in, and you’ll start to see the seventh-wave pattern.
Use the power and directness of the wave to call something to you as you watch it come in. Visualizing your goal, say to the waves:
One and two, three and four,
Leave a token or drawn symbol of thanks at the shoreline before you go.
