Identification of a Buddhist text written in classical Chinese or Japanese

Question

While looking for an answer to this question I found a text that contains the quote in question, but I cannot find any information about it.

• Is it written in classical Chinese or classical Japanese? (The two written languages were apparently quite similar)
• Is it a commentary to the Lotus Sutra as the title seems to indicate?
• When was it written and by whom?
• Are the divisions equivalent to the divisions of the Lotus Sutra?
• Do the line numbers also point to the lines of the sutra?

Answer 1

1. It is classical Chinese written in part of Chinese character and part of Japanese kanji Character, it is still Chinese text, I can identify it because I am a Chinese speaker.

2. Yes it is Lotus Sutra

3. Kumārajīva and Yao Qin translated an ancient book "龜茲文本" to Chinese, that is Lotus Sutra

I can only answer this, I have no information for the rest of questions
