In this context, "hasten" is not present in the quoted lines. However, the meaning of the lines is that the speaker is refusing to leave, and implicitly urging the other person to not hurry them along.
Here's a breakdown:
* "Do not bid me adieu": This means "Don't say goodbye to me."
* "Thus far I have come": This indicates the speaker has already traveled a significant distance or made considerable effort.
* "I will not go back now": This emphasizes their determination to continue their journey, regardless of the listener's desire for them to leave.
Therefore, while "hasten" isn't directly present, the line suggests a refusal to be hurried or rushed away. The speaker is determined to stay and sees no reason to speed up their departure.
