I find the ideas expressed by the venerable to be confused.
The idea that “citta does not change, does not exist but it is real” is nonsense.
None of this lines up with orthodox Theravada at all.
This monk spent 60 years basically meditating at a strict forest temple in Thailand and this is the result. It shows how deep ditthi is and why is is incredibly important to work on right view at the level of pariyatti and sacca ñāna.
On another note "The citta creates a moment of viññāṇa". Viññāṇa and citta are synonyms - citta is not running around creating viññāṇa.
