All sentient beings that we meet (however fleetingly) have been our kind mothers in the many lives we’ve existed in before this life.
One should be mindful of their kindness and the lessons they so graciously extended for our benefit.
It is now our time to repay this kindness.
One should follow wholeheartedly the Buddha’s Way, especially The Eightfold Path to Enlightenment, with complete and calm compassion.
Think pure thoughts and express your Buddha-nature., but always remember to show yourself the same loving-kindness. This will relieve one of the mental anguish one carries within.
