Naturally, there are many material things in the world.
“Sky” is the concept that things do not have a universal essence.
Things are everything, and I, living things, and matter are everything.
For example, let's say you have a 10,000 yen bill.
I am the one who recognizes this as money, and there is no essence of money on this 10,000 yen bill.
If someone who doesn't know money at all sees it, it will be recognized as a piece of paper with a picture printed on it.
Also, it may be paper that blows butts in the toilet, and if you look at a goat, it may look like delicious food.
In other words, there is someone who admits “this is 10,000 yen,” and for the first time, there is money called 10,000 yen.
If it is recognized as “toilet paper” or “goat food,” the essence changes.
This is called [sky], and it is also called [luck] and [selflessness].
If a single thing itself is to exist with an essence that does not change universally, an Atman (soul) is necessary.
You need a soul to exist even when you don't have a partner.
However, Buddhism believes that there is no Atman in everything and explains that it is “selfless.”
Being selfless is empty at the same time, and since it's empty, it changes rapidly when the edge touches it.
It is also expressed as impermanent conduct and various laws and selflessness.
Things exist, but their essence changes from time to time.
What changes is changing depending on how you look at what you are confronting.
The person who recognizes me as “me” is the person I am confronting, and I have a soul, and I am not recognized by the “soul called me.”
I also have no essence, and my essence is empty.
That is one of the major differences between Buddhism and other religions.
Most religions are based on “selfish ideology,” which affirms the “soul.”
The reason why Buddhism does not accept biased obsessions and goes down the middle path is because “everything in the world is empty.”
A life of being obsessed with changing things is a waste of life.
People suffer and die in search of the contents of things that are empty.
