India, Sept. 7 -- Every September, the familiar excitement of Teachers' Day returns. Two days ago, on September 5, we honoured those who shaped our minds-parents, school and college instructors, mentors, and gurus who guided our journeys. Yet, as a botany teacher, my thoughts often drift to a mentor who predates every classroom, textbook, and blackboard: Nature itself. My love for the natural world began in childhood-the soft rustle of courtyard leaves, the earthy petrichor of the season's first rain, a patient squirrel storing food, or a seed pushing through dark soil toward the sunlight. I did not realise then that these were formal lessons, but today I recognise them as my earliest classrooms. Nature teaches patience far better than any textbook. A seed never becomes a tree overnight; it waits beneath the earth, anchoring its roots before risking a tender shoot above ground. A caterpillar endures the cocoon before emerging as a butterfly. Nature operates on a rhythm that reminds us, in our hurried lives, that nothing truly worthwhile can be rushed. It also demonstrates profound generosity. A tree offers shade to a passerby, fruit to the hungry, shelter to birds, and oxygen to every living creature-asking nothing in return. Rivers flow, the sun shines, and blossoms spread fragrance without demanding gratitude or questioning who is worthy of the gift. In a forest, we see peaceful coexistence in practice. Countless organisms occupy the same space: Bees pollinate, birds disperse seeds, fungi recycle nutrients, and trees provide shelter. Life survives not through raw competition, but through intricate interdependence. We are not isolated beings; our existence is woven into a much larger web of life. Nature shows us resilience, too. Trees bend before storms but stand tall when the skies clear. Rivers carve new channels around obstacles. Seasons change-spring yields to summer, summer to monsoon, and winter to new life. Nothing remains static, yet life persists. Perhaps that is why, when I think of my teachers, I think not only of those who stood before me in classrooms, but also of the world outside the window. Nature was always teaching-quietly, patiently, and without a syllabus. So, as the Teachers' Day celebrations wind down and we carry on thanking the instructors who built our intellect, let us pause to acknowledge our oldest and most generous educator. Step outside, listen to the wind, watch a leaf unfold, observe a bird building a nest, or simply sit beneath a tree. We may discover that Nature has been teaching us all along-and unlike the rest of us, it never retires....
