Even boiling water will grow cold right away and go back to its original state
if it is not continually boiled.
Water of the heart also will grow cold right away if it does not heat up.
Even the heart of love that was boiling hot will grow cold right away
if heat is not applied.
Take action steadily/consistently.
Doing things steadily/consistently is the best!
Then you will engage in love that does not die.
