There’s no real happiness among any of the six classes of beings. If we consider the sufferings of the three lower realms, when you feel upset just by hearing about them, how will you possibly cope when you experience them directly? Even the happiness and pleasures of the three upper realms are just like fine food that’s been laced with poison — enjoyable at first, but in the long run a cause of ruin.

-- His Holiness Chatral Sangye Dorje Rinpoche
