When meditation happens you will see two wings growing in you: one will be of love -- Atisha calls it compassion -- another will be of freedom. And they will both start growing together. This brings fulfillment. Then there is no grudge, no regret. Atisha is right; he says:
NOW, EVEN WHEN I DIE, I'LL HAVE NO REGRET.
Life has been a fulfillment. I have known its mysteries. I have loved, I have lived in freedom, I have known all that was needed to be contented. I am utterly fulfilled. Life has been fruitful. Life has not been a wastage, it has been a constant enrichment, and I have bloomed and the lotus has opened.
