Writing this thread as I want to check my understanding from Zen perspective.
Just now I read the web-page at https://terebess.hu/zen/nanyue.html and the below section in this web-page:
When Huairang first arrived, Master Huineng asked, “Where did you come from?”
Huairang said, “From Mt. Song.”
The master asked, “What is it that has come?”
Huairang was stuck and couldn't answer. He then decided to stay and practice there.
_Eight years later Huairang one day said to Master Huineng, “Now I have an understanding.”
The master asked, “What is it?”
Huairang said, “To say or do anything misses the mark.”
The master asked further, “Then is there any real practice to do, or awakening to experience?”
Huairang said, “It's not that there isn't practice and awakening, it's just that they can't be defiled.”
The master said, “Just this that can't be defiled is what is upheld and sustained by all the awakened ones. You are like this, I am like this, all the ancestors in India were like this.”
In the above section - the part that they can't be defiled - for this part, some thought came to my mind, so thought of checking with you all if my understanding is in right direction from Zen perspective. My thinking says: What Huirang meant was - there is practice and enlightenment, but it cannot be defiled. Defiled here means the moment we think I am doing practice and I can attain enlightenment - that moment both practice and enlightenment comes impure. Not that there is no practice and there is no enlightenment, but categorizing something as practice and enlightenment would miss the mark - practice is enlightenment - to carry our idea/notion/thought that there is something like practice, which we should do to achieve something like enlightenment, this idea/notion/thought is what makes the activity we are engaged in a defiled/impure/not complete activity or practice or enlightenment.
So no 'I', so no clinging to any idea and no disliking of any idea - would be the way of not to defile the practice as we will not bring 'I' to the practice - and since ultimate truth or reality is always there and is not dependent on us doing anything, because if it is dependent on us, then it is not unconditioned and it will not always be there, which would negate the Ultimate truth or Ultimate reality itself, because Ultimate truth or Ultimate reality should be something which is always there and so not dependent on us.
