▸Guided by Courage: A Night I Didn’t Face Alone

5.00That night swimming with manta rays was an unforgettable experience, and I have my companions to thank for making it possible. Right before getting in the water, I was genuinely nervous—but they reassured me with calm and encouraging words, guiding me patiently until I felt ready to enter the ocean. They swam beside me to the floating platform, helped secure the buoyancy ring around my ankle, and stayed close the entire time. Although I’m generally comfortable in the water, being in the open ocean for the first time—with nothing but dark, deep blue beneath me—was intimidating at first. But because they were there, I gradually relaxed. Little by little, I shifted my focus from fear to awe, completely absorbed by the graceful movement of the mantas gliding beneath us. Without their support and expertise, I wouldn’t have been able to fully embrace that magical conversation with the ocean. Thank you for helping me push through my fears—and truly embrace the mystery of the sea at night.
