Science and spirituality have something important in common: both center on the process of observation.
In science, we observe nature in its concreteness and then move towards causes, abstract concepts, generalizing theories, experimental repetitions, mathematical descriptions, and statistical models.
In spirituality, we too observe nature in its concreteness, and with similar curiosity, but we then move no further. Instead, we keep observing—the breath, the friend, the water flowing down a river—without judgment and without conceptualization.
While observation for the scientist is a means to an end, it is an end in itself for the sage. Hence also the chasm between them when they talk about ‘reality’.
