If we believe that mind is continuous, our love for others becomes continuous. If we recognise this continuity, we do not trust temporary, tangible circumstances or take them too seriously. Since it is tiring to switch between changing uncertainties, which are inherently impermanent and unimportant, we become less easily influenced by any circumstance. This creates the habit of stability so that our minds are less erratic, our lives are less chaotic, and our feelings for others are less changeable, which causes love to become increasingly deep and loyal.

-- Thinley Norbu Rinpoche
