Regulatory rules often accumulate such that they become unworkable. Several popular proposals have called for a requirement to eliminate two old rules in order to create a new rule. This couldn't possibly work from day one with zero rules, but from just about any snapshot, most regulatory bodies have a series or rules that are low priority, redundant, obsolete or are no longer enforced.
I see the "letting go" akin to eliminating older rules.
I like the idea that you could learn in the morning (accumulating) and pare away clutter in the evening (letting go) and progress on both fronts. A lot of these principles that appear to be opposed, are not always in direct opposition.
