“We constantly graps at those arising phenomena, at this ever changing stream, as ‘me’ and ‘mine’. This habit is going on since beginningless time.”
That’s simply not true. Constantly pushing this speculative idea will only bring yourself more harm and more suffering as one can not disassociate yourself from arising phenomena – is like the people who want to stop thinking process and say the same stuff as you but just change “me” and “mine” to “Thinking” and “thoughts. It’s pure nonsense which I already make clear about. The only thing you can do is to see the futility of things which got nothing to do with self/no self nor the objects of your perception. Even if we take your wrong understanding and play devil’s advocate so the only right thing with “I’m” making would be “I want this I want that, I want to be happy” – this would be proper sakkya ditthi as one realized that “I will never be happy” but “I” itself got nothing to do as it’s just agent which will exists till one attain full Nibbana. Using this as starting point to get yourself rid of yourself is just plain unwholesome as you are not the problem but TANHA and AVIJJA and only permanently getting rid of it one get rids of “I” on Arahant stage. Just yapping around that “I” is a problem one will become mentally ill or end up parroting views without any change in their experience in tanha and avijja.
