When you're old, you get all sorts of failures of hte body with aches and pains and so on.

Even so, those are still part of:

"being absolutely thrilled, absolutely delighted with every motion that my body makes. With everything that my eyes see, my ears hear, my nose smells. There's a delight in the sense that I am able to penetrate that. My consciousness, my intelligence pervades everything I see, feel and think..."

While a very few people mature into that state on their own, most do not.

If you're wife was going to mature into that state without help, it would have happened spontaneously by age 30.
