(To ensure its return)

In natural magic, knots and binding are ruled by the element of Earth.    A
knot or binding represent both intangible goals (such as the return of
loaned property) and they also absorb personal power.  This ritual isn't
intended to force or coerce another to return the book, it affects the book,
not the person the book is being loaned to.

Take the book, and hold it between your palms, sending personal energy into
it.

By hill and wind,
By flame and brook,
By shining moon and sea;
I place a bind
Upon this book
That it will return to me.
Wrap one foot of plain white cotton string around the book, securing it with
a knot.  Make sure the knot is tight, but not so tight that you cannot slip
the string from the book.  As you make the knot, visualize the book
returning to you, again chanting:

By hill and wind,
By flame and brook,
By shining moon and sea;
I place a bind
Upon this book
That it will return to me.

Slip off the knotted cord, and put it in a secret place or spell box.  As
you actually loan the book, again repeat the chant (silently) while
visualizing its return.  Once the book has been returned, untie the cord.
It is done.
