Change is the Law of Nature

Dear Parents, Teachers and Students,

Change is the law of nature. The trees shed their leaves with each season, not in defeat but in hope. They stand bare, waiting patiently, trusting that new life will come. And when spring arrives, they burst forth with fresh, tender leaves — making nature look even more beautiful than before.

Our lives are no different. Change comes to all of us. Sometimes it is sudden, sometimes slow. Often it is painful, for letting go of the familiar is never easy. Yet, every change carries within it the seed of a better tomorrow. It shapes us, strengthens us, and leads us forward.

A New Beginning: Message for Academic Session 2026

Dear Parents, Teachers and Students,

As we step into a new academic session 2026, our hearts are filled with hope and vigour. A new year is a blank page, waiting to be written with dedication, learning, and growth. Let us resolve to do and give our very best in all that lies ahead.

May each of you be blessed with wisdom to discern what is right and to choose it with courage. May our collective efforts — in classrooms, on playgrounds, and at home — bear fruit and bring success in every worthy endeavour we undertake.

Sr.Sheryl
Manager, St. Mary's Senior Sec. School
