for it's a smooth-paced horse
carrying you towards non-existence.
Often life brings unwanted afflictions: sickness, personal problems, career issues, family disagreements, chronic conditions, whatever. It can be so overwhelming to feel that all is lost or the pain will never leave. But the reality is that everything in life changes. Nothing lasts forever.
Recognizing that who you are is so much more than all of the things that happen to you brings a deep sense of peace. Understand that, beyond all doubt, you are the changeless awareness within which all happens. Dissolve into who you are and let "a smooth-paced horse" carry "you towards non-existence."
