You are misconstruing Sunyata as nihilism. A common mistake of those unfamiliar with Buddhistic teachings....
You seem to have not even read my post.
1. I have not said that Sunyata was Nihilism. I said that Sunyata is an experience of "emptiness of all things/objects" and the yogi that experiences is not a thing/object. Such Yogi is not separate from Brahman, which is of nature of Existence-Consciousness-Bliss. I said that those who uphold Sunyata and reject the Yogi are Nihilists.
2. And I have repeated a few times that the Consciousness is not devoid of Being and Being is not devoid of Consciousness.
In all these, I am merely paraphrasing Shri Ramana Maharshi and not airing my own concocted view.
First one sees the Self as objects, then one sees the Self as void, then one sees the Self as Self, only in this last there is no seeing because seeing is being.
(Bhagavan in 'Day by Day with Bhagavan' 21-7-46)
If, as you say, there is 'no second', then one thing cannot become another, because there is no other; no second, just as you claim. Any such 'becoming' is purely delusional.
Again. "Knower of Brahman becomes Brahman" is a Shruti that depicts a Seeker's perspective. Shruti, to a Hindu, is infallible. So, when you use a Shruti "Tat Tvam Asi" and reject another, you are not being impartial ... you are intent upon proving your mental concept and you are resortingg to pick and choose.
Just consider your effort in this thread.Who are you trying to convert to your opinion? If there is any one delusional, as per your own definition, it is you alone.
