All understanding (we aren't talking about knowledge or skill here) can only be beneficial – it cant be right or wrong - and with enough dedication to understanding, we will be able to become the best version of ourselves that we cna be, right now in this very instant.
We can imagine this as a carpenter with certain tools and skills. As a young apprentice their skills are limited: they don't understand the material they are working with yet and they might not be able to control certain tools to work it with. Even so, with full application and concentration the young carpenter will still be producing the very best work that he can at that point in time; in fact it couldn't possibly be any better. With dedication he develops his understanding of the material as well as his skill with the tools and eventually he is producing work that is unrecognisable in quality from his earlier efforts, yet of course, it is still only the best that he can deliver at that point in time. With an attitude of acceptance and non-judgement he would have been just as satisfied with his earliest efforts as as he would be with those when he became a master craftsman.
That is why every time we practice it can only be perfect!
