In this quote from Miguel de Cervantes Saavedra's "50 Masterpieces You Should Read Before You Die: Vol. 1," the idea is presented that harnessing the strengths or resources of an adversary can lead to significant advantages. By utilizing knowledge or strategies from opponents, one can enhance their own power and effectiveness in various situations. This concept highlights the importance of adaptability and strategic thinking in overcoming challenges.

Ultimately, the message encourages individuals to view conflicts or competition as opportunities for growth and empowerment. Instead of merely confronting adversaries head-on, learning from them can lead to innovative solutions and greater influence. By turning the tables on the enemy's strengths, one can achieve a form of dominance that transcends conventional limitations.
