Final answer:
Santiago needs to adapt physically, mentally, and spiritually to survive the harsh conditions of the desert, understand its socio-political implications, and embrace its beauty and challenges.
Step-by-step explanation:
To immerse himself in the desert, Santiago needs to adapt to the harsh realities of desert life. He must become accustomed to the difficult environmental conditions such as extreme heat, scarce resources, and vast openness. Santiago's immersion involves not only physical survival skills but also a mental and spiritual adaptation, embracing the desert's unique challenges and its stark, foreboding beauty.
This means preparing for the unpredictable, such as sudden changes in weather, as well as the emotional toll of isolation and the overwhelming presence of nature. Santiago must also navigate the socio-political landscape, understanding the desperation of those who cross the desert seeking a better life, reflecting on the human cost associated with border enforcement, and finding his own place within this complex context.
