Feeling good is a raised vibration because your natural state is joy. And cleaning your vibration to bring it back to ‘good feeling’ is a really valuable thing to practice. The best way I know of is, when you catch yourself experiencing something less than your natural state… take a deep breath and find something/someone to APPRECIATE or find something that makes you laugh with pleasure.
I don’t know of any better vibration cleaners than appreciation and humor! That’s where I go when I need to get my energy into alignment.
