The most important thing you can do to enhance your experience of existence is this: mental hygiene. In other words, if you’re having an unpleasant time, then you have a dirty mind. Every day, every hour, every minute, you have to tidy up as thoughts ceaselessly blow in through the window of consciousness.
The thoughts themselves aren’t necessarily “dirty”, it’s your own tendency to collect them and clutter up your mind that’s the problem. On their own, thoughts blow in, thoughts blow out — no big deal. But when you hold on to them, storing them away on a shelf for easy access, regularly marveling at them to the exclusion of new thoughts — you’ve got a problem.
Be careful of collected thoughts. Once you take a thought, it’s like plucking a flower off a bush. It’s cool to have it in your house for awhile, but it will wither and wilt soon enough, becoming a decayed version of its former self. And that’s fine, who doesn’t like some fresh-cut flowers around? But, you must maintain the vases and throw-out the flowers when they start to droop.
Who wants ugly or stinky flowers in their home? If a thought is unpleasant, don’t maintain it in your mind. Let it go, move on to the next one — there’s always a new one waiting to come in. Try not grabbing any, just soak in the sights as you browse the thought aisle. Scan past the ones you don’t prefer and focus on the ones you do.
