INTROSPECTION - if one wants to seek truth, would one realise what they knew could've been a lie?

The first thing in seeking truth is parting ways with meaning. It is created as a tool for physical understanding and societal survival (language, social interactions, describing whatever is needed). However, meaning easily gets tainted by psychological and emotional attachments, leaning one further from the real truth of life: you don't need meaning to see and feel life. Meaning is just psychological and externally-oriented. If one seeks the nothingness within (separation from meaning), then their mind (brain) becomes useless here. So if you think you're mentally useless, you might actually be good at introspection!

After all, "waking up" means levels upon layers of realising how much of a slave one has been towards meaning, so therefore how much one has entangled themselves in the futilities of the mind.
