"Kindness (desire to ease burden), Compassion (desire for well-being) , Teaching (nurturing growth), Love (unconditional acceptance) are linch pins for happiness." 2:15 mantra, 6:45 contemplation.

These linch pins are not things that you do as the path to happiness.  Or maybe they are.  You can do these things and not find happiness.  It may be more that when you are happy, you will do these things.  It's sort of circular.  I think it really boils down to self worth which leads to these virtues.  It is hard to be kind, compassionate, nurturing and accepting of others if you cannot do these things for yourself.  We are all deserving of these virtues.  They are markers for happiness, not prescriptions for happiness.  If you are happy, then the virtues follow.  Happiness comes from realization the way you are is in harmony with the universe.  I have trouble finding the words.  It is knowing you are not in conflict with the universe.  It is in choosing not to be in conflict with the universe.  That is not to say you won't be in conflict with other people.  And, maybe it isn't not being in conflict with the universe.  It is knowing when you cannot overcome conflict with the universe and realizing the cost and benefits  of the conflict and how worth it is.  And, conflict itself can be acceptable if you are willing to bear the cost and be at peace with it.

You are worthy of kindness and compassion, nurturing and being accepted as you are.  These virtues are linch pins of happiness and love.
