Understanding the nature of delusion is one of the attributes of waking up, but it’s not the delusion the world is entrapped to that one wakes up to, it’s the delusion that runs your own life.
What is the delusion that runs your life? The delusions manifest as one attaches to their thoughts. The first thought one has about something is inconsequential, it the attachment to the second thought that forms the delusion. To understand delusion one must be aware of their attachments, desires, confusions, and the way your mind works, without this the puppet on string pattern prevails. Certain practices turns one inward to see this, if what you are doing doesn’t turn you inward, you will remain entrapped to your delusional state of mind. This is why nothing from the outside truly changes a person because anything from the outside is part of the delusion. A broken mind can’t fix itself and as long as it’s reaching for something on the outside, it remains trying to fix itself and thus it remains broken. Until this truth is seen, things have to stay as they are because nothing is being done to change it.
We can only know what we know if there’s awareness of it. What this means is one has to develop mindfulness of what they are doing as they are doing it, so there is awareness of what is being done. If you know what you’re doing as you’re doing it, it leaves little room for delusion to arise. Mindfulness is probably the single most discipline to develop as it anchors you in the moment that what is being done occurs. Delusion only occurs when one lives in the story that there’s a past or future. These mind made constructs keeps the delusion alive. The present moment can be seen without making it a story, even though it passes as quickly as it arises. But the past and future can never truly be seen without a story, and because most lack the discipline to be present, most live in a delusional state of existence.
