Ehmm, basically what we need to do in the Natural Liberation is similar with what you describe Ben.
In terms of what we need to do, I don't see a difference.
However, is there a teaching in Theravada saying what will you see or what will you face during the death time.
This teaching is useful in the sense that it prepares us in advance by knowing what are we going to face.
It is like we want to go to Iraq.
If I know the map about Iraq, the culture there, and the people there, I will not shock when I am in Iraq. In this way, I can practice what I need to do smoothly.
But if I don't know Iraq, I can be shock when I experience that.
If in our daily life we have fail to be mindful, to do like what you have describe, it is almost 99% certain that during death, we will also fail. Because the situation is completely different.
If we cannot be mindful, calm and quite Himalaya, it is very unlikely we can be mindful, calm, and quite in the Wall Street.
In this way, the teaching of Natural Liberation is useful. It teaches us and prepare us, what are you going to face there.
Do you see my point?
It is this one, that I want to ask. Are there teachings in Theravada, which explain the situation near death?
I am not here nor there.
I am not right nor wrong.
I do not exist neither non-exist.
I am not I nor non-I.
I am not in samsara nor nirvana.
To All Buddhas, I bow down for the teaching of emptiness. Thank You!
