You have misunderstood the point to the level of "Einstein and moral relativity".

Applied to the context you put (cultivation and others), it's along the lines of "perform surgery while sober vs drunk".

You misunderstood because of the imperfect summary from the commenter, and because of the un-realization that the use language implies very large amounts of interpretational space - explicitly. You have to understand those expressions through the understanding of the full discipline.

And: the context is not in the realm of "I think", it's not a philosophy: it's meant to be research.
