As a Meditation Teacher I teach people to start over when they are meditating and a thought comes in. Don’t beat yourself up... just start again.
I don’t believe life is “trial and error”. There are no errors. “Try and try again” or “try and begin again”. So, why do we beat ourselves up again and again when we become out of alignment?
I noticed today that I would get annoyed and then get annoyed at myself that I let myself get out of alignment. It’s just a viscous cycle. Everyone who is alive gets out of alignment once in a while, no exceptions. So, give yourself a break... and begin again.
