This is a hermeneutic phenomenological study that describes and interprets Wong's, the first author lived experience in the borderlands of science and Buddhist mindfulness as a science education doctoral student in Thailand. I explore my experiences in learning with multiple mindfulness teachers, including Thich Nhat Hanh from Buddhist traditions. and Additionally, I explore the affordances of being in the borderland of science and Buddhism, and how Buddhism can expand the border of science education through the inclusion of important topics, such as mindfulness, emotional wellbeing, and interbeing. This study also examines the roadblocks that are preventing deeper integration of science and mindfulness, including empiricism, scientism, individualism, materialism, and dualism. My standpoint is that to overcome the 21st grand challenges, teachers of science need to have the courage to cross the borders of various disciplines and help students develop essential skills for cultivating a healthy, balanced, and mindful lifestyle.
