Hua t’ou means word-head, that which precedes word. Before a word is said, it is a hua t’ou, the moment before a thought arises. The unending void. Turning of the light inwards, instant after instant, exclusive of all other things, is called “looking into the hua t’ou.” The moment before a thought or mental word stirs in the mind, the precious vajra king sword. Word arises from Mind and Mind is the head of word. Before a thought arises, it is a hua t’ou. To look into a hua t’ou is to look into the Mind.
The hua t’ou sometimes is compared to the Greek logos, which sometimes is said to mean word, and other times seems to mean that which gives form and meaning to the cosmos.
In the beginning was the Word.
I believe Chapter Twenty-Three currently resides in the hua t’ou, and that is where I will find it.
