"The power of thought and the impact it has on the nature of one's life and death cannot be stressed enough. The quality of one's thought is the event. This is not an abstraction. All of the components of life and death arise within your own thought constructs.
People think they can choose the kind of thoughts they will have when they die, but this is not the case. Your life and death are the same, they mirror each other, and the thoughts you hold in your heart and mind during life, are the thoughts that will be present at death.
It is because of this all-important understanding that we engage in spiritual training. We learn to meditate because when meditation is strong, it is like a trip between life and death traveling through the bardo of our own nature.
