Sometimes you just have to declutter the physical then get to the mental and spiritual.
It takes a stronger will to clean up the inside than the outside. But usually when your room or home space is lighter and has a better flow, you also become less sluggish and are able to become more alive.
I've realised though that you should try to clean or clear up both....for once one starts to accumulate dust the other will too.
Life is really a daily process of letting go and holding on.
And also realising that we're in a state of constant flow, for time will never allow us to remain the same even though mentally we might be in the same place.
