To find the comment related nodes, I will look at the higher level nodes. Hence, I can see that the 'block_comment' nodes with ids = [1], represent comments in the code. Incorporating each of these nodes, I can make a general rule to extract the comments.

This python script can be executed:

```py
# As the snippets start with '#[' and end with ']#', we can remove three characters from the start and three characters from the end to get the required snippet
extracted = code_snippet[3:-3].strip()
```

This script will extract the comment from the given code snippet, which is "This is a multi line comment\nit continues until it is terminated\n".
