With a great effort of will he ignored the illusion.

With a super-human effort of will she opened her eyes.

With a fierce effort of will she took herself in hand and began to prepare breakfast.

By an effort of his will he had again become master of himself.

With an effort of will he brought himself to look more closely at her.

With a major effort of will he broke the spell, and stepped back.

With an effort of will she made herself start toward the instrument.

Her eyes fluttered closed; with a great effort of will she forced them open again.

With a great effort of will I gave it to her to open.

With an effort of will she straightened her back; put on authority as if she'd earned it.
