“We are very fortunate to be alive at this point in history when we have access to the teachings of the Buddha. It is a tremendous opportunity for all of us. We have the chance to profit by realizing the path, fruition, and nibbāna that are the most valuable Dhammas. But this opportunity will pass. Unfortunately this great opportunity does not last forever. The span of our lives ends before long. Even if our lifespans are not yet over, we can die at any time. And even while we are still alive, we may lose the ability to practice if we become weak or sick due to old age, if conditions are too dangerous, or if other problems or difficulties arise.”
