Aloha MB,
He may give it a try if he can read Maura's story above. Just be sure to let him know that if he's not visualizing the energy very well that's okay, just imagine it. If he's not doing well imagining it, then he can pretrend it's happening.
Remind him of all the competitive skiers who visualize their runs down the slope many more times than they actually shi it. The body doesn't know the difference and it makes a difference.
You can also visualize your husband coming and standing /sitting next to you during your active exercises or meditation - doing it along side you.
You can also put him inside the ball of energy during the Joining of Yin & Yang exercise as you do it.
Much Love, Shawn
