I created a separate topic because I wanted to focus on a different direction Definition of Ignorance:
4 Noble truths says that I am suffering and enlightenment can be achieved through cessation of ignorant(or wisdom). When I ask what I am ignorant about it says I am ignorant about 4 Noble truths.
This seems circular and not really applicable to practice. I do think I know about suffering intellectually and that does not seem to lead to enlightenment. Someone might say you need to see(vision) suffering - not just faith or intellectual ideas.
From MN9
Ignorance originates from defilement. Ignorance ceases when defilement ceases. The practice that leads to the cessation of ignorance is simply this noble eightfold path.
But what is defilement? What is its origin, its cessation, and the practice that leads to its cessation?
There are these three defilements.
Tayome, āvuso, āsavā—
The defilements of sensuality, desire to be reborn, and ignorance.
kāmāsavo, bhavāsavo, avijjāsavo.
Defilement originates from ignorance. Defilement ceases when ignorance ceases. The practice that leads to the cessation of defilement is simply this noble eightfold path.
So understanding defilements should definitely help us clarify the concept of ignorance.
Types of Defilements:
- kāmāsavo - defilements of sensuality
- bhavāsavo - defilements of being/existence/bhava
- avijjāsavo - defilements of ignorance
Defilements of Sensuality - kāmāsavo
Perhaps this means we assign sensuality to objects that does not have it intrinsically. For example: all colors, lines, shapes are the same without one being better than others. But for paintings which are a collection of them, we assign “beautiful” or “good/bad”. So in this case sensuality is assigned to an object(painting). This leads to not seeing(ignorance) the real nature of the object.
Defilements of sensuality may be also the cause of wilful ignorance. Example: Suppose a person is suffering from an illness that prevents him from eating a certain food. Although he knows it is bad for health, he may still eat it, citing that it’s just one time or perhaps it has less impact on the health. Here it’s clear that sensuality prevents a person from acknowledging the reality.
Defilements of existence - bhavāsavo
From SN 22,
"'“Everything exists”: That is one extreme. “Everything doesn’t exist”: That is a second extreme. Avoiding these two extremes, the Tathagata teaches the Dhamma via the middle
But when one sees the origination2 of the world as it has come to be with right discernment, ‘non-existence’ with reference to the world does not occur to one. When one sees the cessation of the world as it has come to be with right discernment, ‘existence’ with reference to the world does not occur to one.
It seems both existence and non-existence are defilements to seeing the world as it is. Example: A person might insist ‘there is a soul’. It will be hard for that person to see ‘there is no soul’.
avijjāsavo - defilements of ignorance
This seems circular again and I am not sure what it means. But I would think ignorance of being ignorance(or thinking that they know) is part of this.
Summary
- Ignorance: Not clearly seeing due to defilements
- Sensuality defilement:
- Assigning sensuality to objects
- ignoring reality due to sensuality
- Existence defilement:
- insisting on existence or non existence
