The phrase suggests that maintaining a balance between tension and relaxation is crucial. Just as a bow needs to be neither too taut nor too loose, people should avoid extremes in their actions or attitudes. Keeping something overly tight can lead to strain and eventual failure, while allowing it to remain slack may prevent immediate use when needed.
On a deeper level, this quote advises against living life at either end of the spectrum. Being perpetually tense can result in burnout, stress, and diminished performance. Conversely, being too relaxed or complacent can mean missing out on opportunities due to a lack of preparedness. The ideal state lies somewhere in between—being ready and capable without overexerting oneself. This balance allows for resilience and adaptability in various situations.
The quote is attributed to Phaedrus, who was not an ancient Greek philosopher but rather the pen name used by American writer Howard Melvill Savage. Known for his deep insights into human nature and behavior, Phaedrus wrote "The Tao of Physics" and other works that explore connections between science and spirituality. His writing often features philosophical musings presented in a conversational style, making complex ideas accessible to a wide audience.
