(9.156) From time to time, they take a fortunate rebirth
And briefly enjoy some temporary happiness,
But soon they die and fall into the lower realms,
Where they experience unbearable suffering for a very long time.

(9.157) In samsara, there are many pitfalls that lead to suffering.
Instead of finding the path of emptiness that leads to freedom,
We are bound by its opposite, grasping at true existence.
But if, while in samsara, we do not find the path of emptiness,

(9.158ab) We shall continue to experience an unending ocean of suffering
That is so unbearable it is beyond analogy.

Because we do not have deep conviction in the existence of past and future lives, the teachings on the sufferings of the other realms seems abstract or intellectual or philosophical. But let us try set those doubts aside for now and engage in a thought experiment that past and future lives do actually exist and we are bound for them.

What awaits us in samsara? The truth is the vast majority of beings within samsara are in the lower realms. Put another way, the vast majority of our previous and future lives will also be in the lower realms. The reason for this is quite simple: when we take lower rebirth, we engage almost exclusively in negative actions which causes us to remain in the lower realms. Because there is virtually no Dharma to be found, it is very difficult for us to die with virtuous or pure minds and escape from the lower realms.

The sufferings of the animal realms are manifest in obvious. It is worthwhile spending some time watching nature shows about life in the wild to see what life is like for wild animals. It is definitely worth our time to watch the videos about how animals in industrial farming are treated see what their lives are really like.

To get a feel for the hungry ghost realms, we can consider the plight of those who are starving in various parts of the world. It’s not enough to just simply look at the pictures of the emaciated children, but we should spend time researching to try understand what their lives are like and ask ourselves what would we do if we were born in such a situation.

To get some feeling for the hell realms, we can watch authentic documentaries about war. Not the Hollywood glamorized versions of war, but the actual experience of soldiers and the horrors they go through. We can see how just a short period of time in a war zone can permanently scar someone’s mind and leave them crippled with PTSD for the rest of their life. One of the books that marked me the most was a book about how rape is used as an instrument of war. Imagine the terror of women who are captured by enemy soldiers and raped just to be cruel.

If we want to get a feel for what it is like to be born in the cold hells, we should spend the night like a homeless person in a cold city in the middle of winter.  If that is too much, then try to simply sleep a few nights without the heat on in the middle of winter without any blankets. We do not do these things sort of guilt or self-flagellation, but rather to help us move the teachings on the lower realms from something abstract and removed from us to getting a taste for what it is like. The goal is to generate a deep fear of taking rebirth there and a profound compassion for all those who have.

In truth, all of samsara is one giant reviving hell. In the reviving hells, we are killed by enemies and then revived just to be killed again.  Or worse, we are killed in battle and then revived only to begin killing again and continue the fight. One of the most powerful scenes from Game of Thrones is when there was a major battle had a village by the sea and thousands of the Night King’s soldiers were killed. As Jon Snow escaped with a few remaining wildlings, he looked back and the Night King merely raised his hands and all of those killed in the battle rose again as soldiers in his army only to fight another day. It did not matter whether the soldiers first fought on one side or the other, they all equally arose as soldiers in the army of the dead. Such an army is an unstoppable force that promised to devour all life in Westeros.

The night King, however, was able to be killed with Valyrian steel. Arya Stark wielded her Valyrian steel dagger and killed the Night King, causing all of the soldiers in the army of the dead to fall.  The wisdom realizing emptiness is the Valyrian steel that can destroy all delusions. The Night King of our samsara is our self-grasping ignorance. And if we kill this one demon with the wisdom realizing emptiness, we can cause all of samsara to cease.
