The quote from Amy Tan's "The Bonesetter's Daughter" highlights a significant distinction between modern writing tools, like bottled ink, and traditional methods such as using an inkstick and inkstone. It implies that easy access to modern ink allows for a rapid flow of thoughts that may not be valuable or reflective, merely skimming the surface of one's mind. Instead of allowing deep reflection, it delivers superficial ideas akin to "pond scum" and distractions that can clutter our thoughts.

In contrast, the act of grinding an inkstick on an inkstone invites a more mindful approach to writing. It forces the writer to pause and consider their true intentions, promoting a deeper connection between thoughts and feelings. This process suggests that analyzing one’s motivations can lead to more meaningful expression. Thus, it encourages a cleansing of the mind, creating clarity that enriches the writing experience and allows for authentic communication of one's inner self.
