Blissful emptiness. The Buddhist ideal of living without attachment, because attachment is "suffering".

You touch on these things, without being nearly as punchable as Buddhists. Without reformatting your head space occasionally, it gets winrot. Without cleaning your house, it gets that dust layer over everything that subconsciously pisses you off. Without white space, there is no new.

A blank canvas is much easier to create from than a full one. It is not an indulgence to reset yourself. It's an essential and worthwhile practice.
