What does it mean to be 'more in contact with reality' (to me)?

It means to become in contact, in connection to 'the truth of reality', which is: chaos. And inside of chaos: difference, connection/contamination, becoming/change/impermanence.

this 'truth' is anti-essentialist, which makes it untrue if one wants/thinks it to be The Truth.

And to be clear, this 'truth' of chaos, this 'truth' of reality is not a mere cognitive fact, it is not the 'right' outcome of a process of 'reason'. It is an intensely embodied experience, completely embedded in reality and never reducible to a formula or a collection of sentences such as this text.

If you're looking for The Truth, you won't find it in reality. In contrast, this 'truth' exists.

And experiencing more, going deeper while knowing of its lack of an end or bottom is a valid goal in of itself. Because if it is experienced 'truthfully', it leads to connection with and affirmation of life and existence. But also just because it's true.
