Looking at the world today, we might easily forget that the main purpose of our life - you could call it the heart of being human - is to be happy. All of us share the same wish, and the same right, to seek happiness and avoid suffering. Even following a spiritual path, or the religious life, is a quest for happiness.

Sit, then, as if you were a mountain, with all the unshakeable, steadfast majesty of a mountain. A mountain is completely natural and at ease with itself, however strong the winds that try to bother it, however thick the dark clouds that swirl around its peak. Sitting like a mountain, let your mind rise and fly and soar

I remember how people would often come to see my master Jamyang Khyentse simply to ask for his guidance for the moment of death. He was so loved and revered throughout Tibet, especially in the eastern province of Kham, that some would travel for months on end to meet him and get his blessing just once before they died. All my masters would give this as their advice, for this is the essence of what is needed as you come to die: "Be free of attachment and aversion. Keep your mind pure. And unite your mind with Buddha."

Ask yourself these two questions: Do I remember at every moment that I am dying, and that everyone and everything else is, and so treat all beings at all times with compassion? Has my understanding of death and impermanence become so keen and so urgent that I am devoting every second to the pursuit of enlightenment? If you can answer "yes" to both of these, then you really understand impermanence.

Speak or act with a pure mind and happiness will follow.

Death is a vast mystery, but there are two things we can say about it: It is absolutely certain that we will die, and it is uncertain when or how we will die. The only surety we have, then, is this uncertainty about the hour of our death, which we seize on as the excuse to postpone facing death directly. We are like children who cover their eyes in a game of hide and seek and think that no one can see them.

We must never forget that it is through our actions, words, and thoughts that we have a choice.
