Do not think it is love, when it is attachment and expectation. So many relationships are built on attachment and expectation, not love.
Love is the wish for the other to have happiness and the causes of happiness. And love expects nothing in return.
Whatever relationship that you have with the other being, when you say that you love them, ask yourself, “Do I love them this way?”. If not, it is not true love.
~ Chamtrul Rinpoche
