There is a HUGE different between these two terms:
1. Cleaning the floor because there is a dirt.
2. Not cleaning the floor because that dirt is actually not a dirt.
It is extremely difficult for dualistic people not to see dirt as not a dirt. Therefore, when the practice buddhism, they try so hard to get rid of this, get rid of that. Get rid of anger, get rid of jealousy, etc. They want to keep a distance with anger, jealously, hatred, and so on.
Why they want to get rid of it? Because they FAIL to see the true face or the true nature of anger, jealousy, hatred, and so on.
For anyone who fail to see the true nature or true face of anger, jealousy, etc., they will try to make themselves as far as possible for all those negative things. They create distance. Huge distance.
Why do you create distance? Because we see they are negative. Why we see they are negative? Because we fail to see their nature.
If we can understand emptiness of self perfectly, there is no such thing call negative, postive, or neutral. You cannot impose any value on anything.
WHen the anger appear, if you fail to see the nature of anger, at that moment you will straight away put a sticker - this anger is negative, destructive, I must do something to get rid of it. What do you do then? Instead of being in the state of anger, you change your attention to breathing, etc.
This practice is good. But it is weak. You will always like a sick person who always need a medicine.
Heart sutra doesn't teach us in that way.
Heart sutra present thing in the negative way.
Why? Because it tells us straight away, directly to heart of the issue:
In that anger, there is no anger.
In that suffering, there is no suffering.
Whatever possible things you can think about, is always always not there.
If someone come and torture us, for sure we will say this is unbearable suffering. It is extremely difficult to say this is not suffering.
But, if you cool down and slowly see the whole process, they are just the flux of phenoma. They are the transient phenomena. They are the dance of appearances.
They have so many varieties of colors, tastes, experiences, etc. But all of them, no matter how complex and complicated they are, they are as simple as the flux of phenomena.
We like to say like this:
THere is no self, but please abandon this.
THat is wrong.
From the subject point of view, you absolutely say there is no something called self.
But, in the second part, you say abandon this.
When you say abandon, at that moment you have reinforce the self. You cannot run away.
If you declare the predicate, no matter how good you are in declaring no self, you have actually deep inside you, you have declare the self. Unavoidable.
For those you know the nature of things: there is no different at all the state of jhana and the state of anger.
Both of them are just transient thing. Because you can see they are just transient thing, the jhana state has no chance at all of bind you. The state of anger also has no chance to disturb you.
Instead, within these two states, you will absoluty serene when the show of anger play, and you will absolutely serene when the show of jhana play.
THey have different colors, but they are just transient.
Jhana state is not better than the anger state, Anger state is also not better than jhana state.
Why don't you do something, like abandon something, change something, transform something?
Because you can see clearly:
Inside anger, it is not an anger.
Inside Jhana, it is not a jhana.
Inside suffereing, it is not a suffering.
They are purely transient and flux phenomena.
There is no suffering, no increment, no decrement, inside all those phenomena, because you cannot have any self of suffering, any self that can increase, and any self that can decrease.
There is also no self that can suffer, and no self that can happy.
That is why boddisattva after they reach enlightenment, they don't stay in the fake meditative state to experience the bliss. They see clearly, in the hell, there is also bliss for anyone who realize non-duality.
They don't need to purposely sit and meditate, because they see clearly the meditative state has exactly same nature with the nature when you don't meditate. Transient.
Because they realize actually they are always inside transient, they are always in meditate state.
Heart sutra certainly negate the 4 noble truth in their any possible existence we can think off.
4 noble truth can only stand if you have SUBJECT, and if you have self.
4 noble truth is designed by buddha to suit us who has a believe there is a self. This teaching is built based on the assumption and foundation there is a self.
4 noble truth is important, because we start from dualistic mind. We need that
But, once you are mature in getting rid of dualistic mind, you must know its limitation - which is standing on the foundation of self.
Because there is dualistic mind that grasp at self - 4 noble truth is a diamond teaching.
When you realize there is no self - 4 noble truth is alient.
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!
