I will say right up front that in my view and personal experience, I find it helpful to differentiate between resting, relaxing, and laziness and not to regard these three activities as being synonymous. Not to say there is anything wrong with equating these three as being the same, I myself just simply do not see them all in the same light.
I regard laziness in similar accord with sloth, which is one of the Five Hindrances in Buddhism and one of the Seven Deadly Sins in the Christian faith. So I find it important to distinguish the difference between what it means to be lazy and what it means to rest or relax.
In my view:
Resting is an art and an important element of self-care and involves quieting and slowing down both the body & the mind. Outside stimulus needs to be at an extremely low level in order to develop the art of resting, so binge watching Netflix doesn’t count here. Falling into media consumption is not resting.
Relaxing involves engaging in an activity that allows us to unwind and/or recharge our energetic fuel tank, such as: fishing, gardening, knitting, cooking, painting, woodworking, watching a movie or show, reading, doing a puzzle, playing a video game…
Laziness, on the other hand, is a deflation of energy and is the mark of a deteriorating, woeful spirit that is moving in the direction of giving up or sinking into the pits of despair.
