How to live and die

What death is, how we die, what minds we need at death and what happens after death—only by knowing about death and rebirth can we actually fully understand what life is and so learn how to live fully.
—Lama Zopa Rinpoche

There is arguably no truth more foundational to Buddhism than this: everything is impermanent. We can see this in the world all around us; old systems break down, relationships change. Death comes for those we love and, inevitably, for us.
